BitSong FanToken (x/fantoken) factory for token staking voting module

[NoahSaso]

btsg-ft-factory

Serves as a factory that issues new fantokens on BitSong and returns their denom for use with the dao-voting-token-staked voting module contract.

Instantiation and execution are permissionless. All DAOs will use the same factory and execute Issue to create new fantokens through TokenInfo::Factory during voting module instantiation.
