Flag ratios

[hexaclue]

Some flags (e.g. the bisexual flag, or the paragender flag) do not have a standard ratio of colours. For example, the bisexual flag has a ratio of 2:1:2.

Fix:

• A file with a map (just like /src/lib/constants/flagColours.ts), containing the ratios per flag.
  • Note that this should only contain flags which have ratios that are not all 1, for efficiency sake.
  • <String, number[]>
• Use these ratios in drawToCanvas.
