Provide better info for Tangut

[jamesohortle]

Although Tangut is extinct and only reconstructed phonologies exist, it would be nice to find a reputable source for phonologies and include them. Currently Tangut characters have unhelpful descriptions:

𗀀 Tangut ideograph L2008-0008 (UnicodeHover)

Desired:

𗀀 Tangut ideograph dow1 (L2008-0008) (UnicodeHover)

Furthermore, we should probably figure out how to better transmit the reference/source for the characters, defined here.

This website Tangut.info provides phonetics for characters from Lǐ Fànwén's books 夏漢字典 (1997 & 2008 eds).

We may be able to request use of the data.

This site provides a DB with ~6000 phonetic transcriptions. Need to contact author and ask. EDIT: Author is Marc Miyake, PhD, currently working at the British Museum, it would appear. Have emailed.

Have added Marc Miyake's data to the Tangut descriptions.
