feat: Bitmapfont add cachebuster & compress

[h1ve2]

BitmapFont (sdf/msdf)

• add cachebuster
• support mipmap
• add compress
• add support for cachebuster for existing BMFont Bug: Bitmap font XML not phrased and exported correctly #88
• use a custom configuration file for sdf/msdf.

Note: To be compatible with compress, the output file name has been changed to xxx.[png|webp|...].fnt.
There should be no impact for projects using a manifest.
If you need to use xxx.fnt by default, please let me know, and I will take the time to modify it so that xxx.fnt is used without compress.

• [nitpick] The test could be more comprehensive by adding more edge cases to ensure robustness.

• [nitpick] The function name 'createName' is ambiguous. It should be renamed to 'generateScaledName' for better clarity.

• The 'resolve' call is nested inside the 'generateBMFont' callback. If 'generateBMFont' throws an error synchronously, it will not be caught by the 'reject' call. Consider adding a try-catch block around 'generateBMFont' to handle synchronous errors.

resolve({ textures, font });

• The new behavior introduced by 'createName' and 'mergeCharset' functions should be covered by tests to ensure they work as expected.

The function transform uses formats.map to create new assets but does not handle the case where formats might be empty. Add a check to ensure formats is not empty before proceeding.
