Issues with languages

[morethanbooks]

• Albanian.xml: language code is in the metadata table right now "als". This is Tosk Albanian (https://iso639-3.sil.org/code/als). In the TEI file it is "alb", which is the code of the macrolanguage. I would keep "alb"
• Arabic.xml: in the table the code for Arabic is "arb" and in the XML file is "ara", which is the code for the macrolanguage. I would use "ara" in both files.
• Aukan-NT.xml: in the table and XML file is the code "djk". However, the SIL and wikipedia prefer "Eastern Maroon Creole". Wikipedia gives Aukan as possible name, SIL does not.
• Campa-NT.xml: the name of the language in the corpus is Campa, but both SIL and Wikipedia prefer Asháninka: https://iso639-3.sil.org/code/cni https://en.wikipedia.org/wiki/Ash%C3%A1ninka_language
• Chinese.xml: the SIL calls it Mandarin Chinese (https://iso639-3.sil.org/code/cmn). I would consider call it like that.
• Jakalteko-NT.xml: in the table the code is "jai", in the XML file is "jak". Actually, I would use "jac": https://iso639-3.sil.org/code/jac
• Myanmar.xml: both Wikipedia and SIL use the term "Burmese" and not "Myanmar", I would use "Burmese"
• Ojibwa-NT.xml: both in the table and XML file the code is "ojb". This is the code for Northwestern Ojibwa; Ojibwa has the code "oji". I would use "oji".
• Quichua-NT.xml: both in the table and XML file the code is "quw", which is the code of "Tena Lowland Quichua". The code for Quechua or Quichua is "que". I would use "que".
• Syriac-NT.xml: in the table, the code is "arc", which is a code for Aramaic. In the XML file, the code is "syr", which is correct. Correct it in the metadata table.

Addressed most of the issues with #39 - let me know if all looks good and I can merge.

For Aukan, Wikipedia, Glottolog, and WALS list either Aukan or Ndyuka as a name (together with Eastern Maroon Creole). I would trust the typology databases over SIL but happy to change if it's more important for the community.
