ttyp0 changes (remove Thai and Hebrew), generator fix

[rohkea]

This PR does the following changes:

• ttyp0: removes scripts that are broken in the current renderer (Thai and Hebrew) — resolve #2999,
• ttyp0: moves the letter F left 1px, to make sure it lines up in menus (requested in the chat),
• generate_cxx_font.rb: fixes the folder (fonts are now in src/generated, not in src)

I'm not sure about the F change. The previous version looked better in running text (but worse in menus), the new version looks better in menus (but worse in running text). Here's before and after:

Thanks for the fixes. Imo the new F looks worse (as running text is more common than menus). Maybe shift the E instead one pixel to the right?

[rohkea]

Here is version with E shifted to the right:

And here are some examples of the running text.

Original:

F shifted to the left:

E shifted to the right:

Okay this triggers now all that want the D and the E | at the same location.

And we cannot move all upper letters by one to the right, this will look bad in other situations.

This doesn't look solvable without redoing the font... So lets just undo this part.

[rohkea]

I've removed the change of the F letter, reverted the original version.

I've checked, the PR doesn't change Shinonome (the case when Ruby version influences the final file, because of encoding issue), so it can be merged (I hope)

Renamed .bin into .bit, thanks for noticing!
