Incorrect Supply Saved on Fungible Assets

[kespinola]

Issue

The column type for supply is bigint but some mints have a supply which exceeds this. There exists a as i64 to cast the supply but instead of throwing an error this sets the number to a negative value.

Bonk is one such example where the supply is 9291438607932069555 outside of the range of i64.

The asset is indexed but when its time to query it this filter for only positive supply triggers.

Fix

1. Switch numeric column type for supply.
2. Bring in bigdecimal to handle "large" numbers
3. Error in case of failed type conversion
