PR: Update Material Design Icons to 5.9.55 and add support for new mayor version 6.x - 6.3.95

[kumattau]

This PR is for updating Material Design Icons to version 6.3.95.

Compared to previous bundled version 5.4.55,

• License is changed from SIL Open Font License to Apache License Version 2.0.
• The number of icons are increased from 5555 to 6395, but breaking changes (some icons are renamed or removed) are introduced in version 6.1.95 (RELEASED - Version 6.1.95 - Breaking Changes Templarian/MaterialDesign#5409).

I think this PR can be merged if the breaking changes are no problem.

Hi @kumattau thank you for the work here!

Regarding the breaking changes we will need to review them carefully since probably applications using QtAwesome could break as for example Spyder (which is something that happened before). So first, we need to plan better the introduction of font breaking changes which maybe should be reflected in the version of QtAwesome (then this should be included for a QtAwesome 2.0.0 release) or think if QtAwesome should help keeping some level of compatibility when doing the font updates.

What do you think @ccordoba12 ?

Note: https://dev.materialdesignicons.com/upgrade to check the removed or renamed icons

After talking with @ccordoba12 we think that the best approach could be to add another prefix for Material Design 6.x (something like mdi6) and instead update the current mdi prefix to use the latest 5.x Material Desing version (5.9.55). With that we think we can assure better compatibility. What do you think @kumattau ? Would you like to work on that ? Let us know !

[kumattau]

I can do updating Material Design Icon 5.x to the latest version and adding new mdi6 Material Design Icon 6.x in a few day.

The point I'm concerned about breaking changes is:

• a few icons are removed or renamed between minor versions. Is it acceptable ?
  https://dev.materialdesignicons.com/upgrade#5.3.45-to-5.4.55

• If each version is bundled with each update, the whl size will increase (Material Design Icon 6.x is 1MB over).

Thanks @kumattau ! And regarding the concerns:

a few icons are removed or renamed between minor versions. Is it acceptable ?
https://dev.materialdesignicons.com/upgrade#5.3.45-to-5.4.55

We are currently bundling Material Desing 5.4.55 so from what I checked the update will only include the rename of an icon (a change introduced from 5.4.45 to 5.5.55) which we will need to readd after generating the *-charmap.json. The other changes between version seems like only new icons but we will need to carefully check just in case (and even in the future maybe figure out a way to do those checks and corrections automatically as well as provide a way to fallback to a default icon or some other handling).

If each version is bundled with each update, the whl size will increase (Material Design Icon 6.x is 1MB over).

That's quite true. Maybe we should only keep at most two mayor versions for the font sets we support. So for example, if we add support for Font Awesome 6 (which is in now beta but in the future could be added here) we should drop Font Awesome 4.7

If you have more concerns or ideas let us know @kumattau !

[kumattau]

we will need to readd after generating the *-charmap.json.

I will work manually, so I think updating the automatic script need to be considered separately.
