Support for optional counter types for ordered list

[jscastanos]

The current version has a fixed list of counter types, which are the default options for ordered list.

So this PR allows an optional way to specify a list on what counter types should be visible.

Example

 tools: {
        List: {
          class: List,
          config: {
             counterTypes: ['numeric', 'upper-roman']
          }
        },
      },

Closes #128

it seems, that user could specify empty array (or array with one value) for counterTypes, then Counter type option should not be displayed in tool settings (since it would never be a choice)

you can add this changes and then it would be ready to merge, thanks for contributing!

Hi @e11sy, sorry I was busy this past few weeks. I've updated the PR. Feel free to review again. thank you

[e11sy]

if we will have 1 counter type, than it would be information plate, not a tune, better to add tunes, when user could change smth

Suggested change

	if (orderedListCountersTunes.children.items!.length > 0) {
	if (orderedListCountersTunes.children.items!.length > 1) {

[jscastanos]

yeah it make sense. kindly review the PR again thanks @e11sy

[e11sy]

can we use typeof Object.values of the OlCounterTypesMap to show, where it all goes from?

[jscastanos]

I agree with that since we have the values already in the map. I pushed a change in this line.

[e11sy]

several small changes and feature would be done, thanks for improvements

[e11sy]

sorry for delay in reviewing, now it seems fine, thanks for contributing

[e11sy]

can you update version to 2.0.6 please, 2.0.5 is already release

[jscastanos]
