Ability to remove ID's/classes, make HTML more clean

I feel like this needs to be looked at soon.

Referencing a bug report I made earlier: Block ID identical after duplicate

I am running into issues with duplicate IDs and Cwicly default classes when using reusable blocks. Copy-pasting using Cwicly’s function is not a problem, but Gutenberg duplicates the class names.

This causes issues where a previously defined element affects a current element, or changes made to one specific element ends up changing a series of others, because they share the same default class.

In addition to adding unnecessary CSS, it’s a source of frustration for me, as I’m having to go back and forth to undo changes made that affect other elements inadvertently and losing a lot of time in the process.

Hopefully we can get a fix for this soon.
