Fix font weights

This fixes a bug that Bold is interpreted as a standard font style (instead of Book) by some applications and operating systems.

Remove canvas depenency which causes issues

This removes the canvas dependency that caused problems. It was only used to generate the preview images.

Fix invalid package-lock

The package-lock.json file included invalid references to packages. This was causing errors when trying to install.

Fix italic ligatures slating wrong direction

This release fixes an issue with some of the italic ligatures slanting in the wrong direction #160

Fix issues with ligatures in italic

This release uses a new way to patch the font files. It uses feature files (.fea) to build the necessary tables. It turns out that the fonttools package (the one that provides the ttx command) includes a way to import feature files.

This process is similar to how FIra Code works. I plan on supporting more ligatures and hopefully will be able to use this technique to handle some of the more advanced features as well (like unlimited arrows, context-sensitive spacing, etc.)

Fix multiple profiles support and naming table

The tool supports generating multiple versions of fonts with different ligatures and names. Apparently the script was broken and never ran correctly for the non-default profiles. This has been fixed.

Also @Jakob6174 found an issue with the naming table not being consistently updated. This affected the Mac font generation. Thanks Jakob!

Add less_hyphen_greater ligature to all weights

This release includes the new ligature less_hyphen_greater by @CandySunPlus.

Add w_w_w ligature for Operator Mono SSm Book/Italic

This release adds the w_w_w.liga ligature to Operator Mono SSm Book/Italic.

I realize this is a controversial ligature, so if you do not like it, you can remove it from your build by following the directions in the README for "Customize your generated font".

Add a file named profiles.ini to your ./original folder with the following contents. This will exclude that ligature from your font when you build.

[default]
!w_w_w.liga

Add Operator Mono Book/Book Italic ligatures

This release finally adds some more non-ScreenSmart fonts. These are the Book/Book Italic weight.
