ef0599d915 get-balance API
Added: get-balance API to fetch total balance
- accepts 2 parameters: floID and token. Requires atleast one of them for the API to work
/get-balance?floID=<floID>&token=<token> : responses balance of a specific token for a floID
/get-balance?floID=<floID> : responses all token balance for a floID
/get-balance?token=<token> : reponses balance of a specific token for every floID

Note (optional): in GET request
- floID=<floID> can be replaced with addr=<floID>
- token=<token> can be replaced with asset=<asset>
Both responses the same result as above
