Suggestion: add support for ȳ

[LEOYoon-Tsaw]

Currently the font supports y with many marks on it, such as ý ỳ ẏ ŷ ÿ ỹ But ȳ is left behind. The dash on top is supported for many other letters, such as ā ē ī ū and many other IPA letters with U+0304 Combining Macron.

The code point support is informed by the character sets defined here: https://github.com/adobe-type-tools/adobe-latin-charsets – ȳ would be part of the largest character set, AL-5.

BTW – since Source Sans has support for the mark feature, you can enter the same combination by using a combination of y and ̄ (U+0304 COMBINING MACRON)

I will add this character in the next major update.
