Create @bitsongjs/fantoken package

[DavideSegullo]

We should create a package to generate the fantoken metadata. Currently on sinfonia-ui we use files saved on github for configurations related to fantokens, I would suggest moving them to IPFS.

This would allow different applications to easily access the fantoken information.

For example we can move this piece of data from assetlists to IPFS:
