New languages added via providing auto.tsv and data.tsv in corresponding language folder, adding the flag information in flags.txt and modifying index.xml file.
1. auto.tsv and data.tsv should be in Tab-separated format and follow newline rules of Firetongue: https://github.com/larsiusprime/firetongue
2. Flags file format supports either loading of custom mod-image or using prebuild one.
Format is:
<language ID>:<type>:<type_data>
Type is either `font` or `image`. Font accept 2 parameters - font name and character. Image accepts asset ID.
For font usage it would be:
ch-CH:font:icons:5
This will use font `icons` and character `5` as flag icon.
For images it's:
ch-CH:image:langMod/flag_china.png
This will search for image located under `landMod/flag_china.png` asset path.
