spl-token transfer failure due to lack of priority fee

[Crypto2]

Problem

Due to how busy the Solana network is the included program spl-token to transfer tokens fails with the error "unable to confirm transaction. This can happen in situations such as transaction expiration and insufficient fee-payer funds" most of the time. (The fee-payer account has 25+ SOL in it so it's not that.)

As I understand it this is due to the spl-token program not adding a priority fee.

Proposed Solution

Update the spl-token program to include a priority fee.
