Font NotoSansBalinese Regular

Issue Noto sans Balinese does not provide the glyphs necessary to write certain conjunct stack; namely the third level stack for YA, RA, RA REPA, LA, and WA. This is required to write certain words such as munggwing, mantra, etc; all fairly common words in Balinese literature. Instead, conjuncts in Noto sans Balinese clashed together in a single space.

Character data

This behavior applies to semivowels ya, ra, la, and wa:

ᬬᬭᬮᬯ U+1B2C BALINESE LETTER YA U+1B2D BALINESE LETTER RA U+1B2E BALINESE LETTER LA U+1B2F BALINESE LETTER WA

Tumpuk telu also applies to two vowel signs: ra repa and ra repa tedung. They exhibit similar shape to ra, but with different input sequence.

ᬺ ᬻ U+1B3A BALINESE VOWEL SIGN RA REPA U+1B3B BALINESE VOWEL SIGN RA REPA TEDUNG

I believe I've fixed all of these apart from third-level la, which will need some drawing.
