Upstream add bank with bump

[lmvdz]

I had issues with creating a bank_with_seed via CPI.
The bumps that I was generating on my program (before CPI) were not matching the bumps stored on the bank (post CPI).
I've added an extra function to support passing explicit bumps to be stored on the bank.

In the bellow image you can see that I am printing out each bump that is received via CPI.
The line lv {liquidity_vault_key}, bump {computed_bump_during_instruction} shows what the bump should be (matches what I am sending through CPI). This is found using Pubkey::find_program_address()

The following bumps are available to be explicitly set.

liquidity_vault_bump
liquidity_vault_authority_bump

insurance_vault_bump
insurance_vault_authority_bump

fee_vault_bump
fee_vault_authority_bump
