Hot fix for #510: Primes need to be angled.
Transplan glyphs for U+203[2-4] (prime, double prime and triple prime)
from NotoSerif* v3 to NotoSerif v2.
v3 has upem of 1000, while v2 has upem of 2048. So, before transplating
glyphs, the glyphs for three characters are scaled up by a factor of
2048/1000. In addition, htmx table was also updated (lsb and width).
The following script was used to transplant glyphs and bump up the
version number to 1.07 from 1.06.
Note that only unhinted NotoSerif-*.ttf are updated and hinted
NotoSerif*.ttf are left alone.
