DynaView: Remove optisizer functionality

It was slow and clunky, and turned out to be easier to do in CSS.

!! Font "Optisizer"
The background task can optionally dynamically optimise the font size of a passage of text to match a desired line length.
* Set the configuration tiddler $:/config/DynaView/Optisizer to the text "yes" to enable this feature
* Optionally, update the configuration tiddler $:/config/DynaView/Optisizer/Text with the "maquette" -- a character string matchng the desired length (this string should not include spaces).
* Assign the following CSS classes to appropriate elements on the page:
** `.tc-dynaview-optisizer-site` for an HTML element whose `offsetWidth` property gives the desired output width
** `.tc-dynaview-optisizer-maquette` for an HTML element that will contain the maquette
* The computed optimum font size can be found in the tiddler $:/state/DynaView/Optisizer/FontSize
The tiddler $:/plugins/tiddlywiki/dynaview/optisizer-maquette contains an example configuration that can be used to adjust the size of tiddler body text. To use it:
* Set $:/config/DynaView/Optisizer to the text "yes"
* Set $:/themes/tiddlywiki/vanilla/metrics/bodyfontsize to `{{$:/state/DynaView/Optisizer/FontSize}}`
* Set $:/themes/tiddlywiki/vanilla/metrics/bodylineheight to `1.5` to ensure that the line height matches the font size
