Before this pr transferring a large amount of an asset would check that transferring the asset would not overflow the supply of the asset. However, it doesn't make sense to check for asset supply overflow when we just transfer from one account to another account and don't increase the supply in any way. It also required to extend the `can_deposit` method of `fungible` and `fungibles` with a `mint` parameter. If this parameter is set to `true`, it means we want to mint the amount of an asset before transferring it into an account. For `can_withdraw` we don't need to add an extra parameter, because withdrawing should never be able to underflow the supply. If that would happen, it would mean that somewhere the supply wasn't increased while increasing the balance of an account.

fortunately, all of this complexity can probably be re-written and removed once transactional storage by default is implemented |

Before this pr transferring a large amount of an asset would check that transferring the asset would
not overflow the supply of the asset. However, it doesn't make sense to check for asset supply
overflow when we just transfer from one account to another account and don't increase the supply in
any way. It also required to extend the
can_depositmethod offungibleandfungibleswith amintparameter. If this parameter is set totrue, it means we want to mint the amount of anasset before transferring it into an account. For
can_withdrawwe don't need to add an extraparameter, because withdrawing should never be able to underflow the supply. If that would happen,
it would mean that somewhere the supply wasn't increased while increasing the balance of an account.
