more work on vanilla repl: repl web component + package + MicroRepl

[felixroos]

follow up for #865 including:

new repl package with strudel-editor web component

There is now a new package @strudel/repl that can be used to easily get a repl running in any html file:

<script src="https://unpkg.com/@strudel/repl@0.9.4"></script>
<strudel-editor>
  <!--
s("bd(3,8)")
-->
</strudel-editor>

The fixed version number will make sure the pattern continues to work. Instead of a fixed version number, latest will give the latest version..

MicroRepl

This is the new version of MiniRepl, using just a thin react wrapper around StrudelMirror to be usable in the docs.
It can be tested in /recipes/recipes-next which replaces all usages of MiniRepl with MicroRepl.

i think I'll merge this first and then start refactoring the docs, replacing MiniRepl with MicroRepl. The refactoring of the main repl should probably come last
