Add common styling options (#27)

[dest81]

Fixes #27.

This PR adds text formatting options for cells, allowing users to apply bold, underline, italic, and strikethrough styles.

Thank you for this @dest81 !

I was thinking we make these configurable. e.g. for our use case, we don't want the styling options.

Also, while at it, it makes sense to align it a bit with the Wagtail ones. My thinking in #27 was to have these off by default, but configurable per widget (features - a list, cross-referenced with the allow list. Defaults to empty):

• bold
• italic
• strikethrough
• subscript
• superscript
• blockquote
• code

As a follow-up, I think it will make sense to add global settings (e.g. WAGTAIL_TINYTABLE = {"features": [...]}) as we'll need to think about the page/document chooser too.

Understood... On it.

Nice work!

Left a few suggestions for readability/clarity.

Needs tests and we're good to roll

@zerolab I have applied all your suggestions and added tests.
