fix: Font styles and width and height of nodes (#2385) 

* Multifont node and edge labels
* adjust documentation
* rework mod-font property inheritance
* Node max/min widths, min heights; Edge max widths
* Accumulate sizes correctly for unconstrained multipoint labels
* handle font.multi when groupOptions.font is not declared
* propagate label fonts on changes, not just creation
* Allow top-level constraint numbers
* accumulate width and empty lines appropriately

<p>
The <code>html</code> and <code>markdown</code> rendering is limited: bolds may be embedded in italics, italics may be embedded in bolds, and mono-spaced may be embedded in bold or italic, but will not be altered by those font mods, nor will embedded bolds or italics be handled.
The only entities that will be observed in html are <code>&amp;lt;</code> and <code>&amp;amp;</code> and in <code>markdown</code> a backslash will escape the following character (including a backslash) from special processing.
Any font mod that is started in a label line will be implicitly terminated at the end of that line.
While this interpretation may not exactly match <i>official</i> rendering standards, it is a consistent compromise for drawing multifont strings in the non-multifont html canvas element underlying vis.
</p>
<p>This implies that four additional sets of font properties will be recognized in label processing.</p>
<p class="indented"><code>font.bold</code> designates the font used for rendering bold font mods.
<br/><code>font.ital</code> designates the font used for rendering italic font mods.
<br/><code>font.boldital</code> designates the font used for rendering bold-<b><i>and</i></b>-italic font mods.
<br/><code>font.mono</code> designates the font used for rendering monospaced font mods.</p>
<p>Any font mod without a matching font will be rendered using the normal <code>font</code> (or default) value.</p>
<p>The <code>font.multi</code> and extended font settings may be set in the network's <code>nodes</code> or <code>edges</code> properties, or on individual nodes and edges.
Node and edge label fonts are separate.</p>

<p>Nodes may be set to have fixed, minimum and maximum widths and minimum heights.
Nodes with minimum heights may also have a vertical alignment set.</p>
<p>Edges may be set to have maximum widths.</p>
<div id="mynetwork"></div>
<p>The <code>widthConstraint: value</code> option means a fixed width, the minimum and maximum width of the element are set to the value (respecting left and right margins). Lines exceeding the maximum width will be broken at space boundaries to fit.</p>
<p>The <code>widthConstraint: { minimum: value }</code> option sets the minimum width of the element to the value.</p>
<p>The <code>widthConstraint: { maximum: value }</code> option sets the maximum width of the element to the value (respecting left and right margins). Lines exceeding the maximum width will be broken at space boundaries to fit.</p>
<p>Minimum width line sizing is applied after maximum width line breaking, so counterintuitively, the minimum being greater than the maximum has a meaningful interpretation.</p>
<div class="sep"></div>
<p>The <code>heightConstraint: value</code> option sets the minimum height of the element to the value (respecting top and bottom margins).</p>
<p>The <code>heightConstraint: { minimum: value }</code> option also sets the minimum height of the element to the value (respecting top and bottom margins).</p>
<p>The <code>heightConstraint: { valign: value }</code> option (with value <code>'top'</code>, <code>'middle'</code>, or <code>'bottom'</code>, sets the alignment of the text in the element's label to the elements top, middle or bottom (respecting top and bottom margins) when it's height is less than the minimum. The middle value is the default.</p>
<div class="sep"></div>
<p>Node width and height constraints may both be applied together, of course.</p>
<p>The constraint options may be applied to elements individually, or at the whole-set level.
Whole-set node and edge constraints are exclusive.</p>
