becoming a sort of dev ux standard + saves on compute inside program instructions, which is something we could feasibly care about - rn a full renew takes up ~15k/20k compute units

main tasks here:

• for all existing PDAs (besides token/mint accounts)
  • add a bump field in the state.rs
  • if the program initializes the PDA, make sure to initialize it with enough space to hold the bump
  • whenever that PDA is passed into an instruction and validated, use create_program_address and include the bump as a seed
    • change the current check_pda helper to maybe take in another with_bump: bool parameter and use create_program_address or find_program_address based on that
    • OR add a check_pda_with_bump function

note:

• for Subscription metadata, please add the bump at the end of the struct because my initialize.js script deserializes some stuff with kinda hardcoded values so adding it at the beginning would break that, but at the end its all good.
• also for subscription metadata, store the count seed

also:

• if whoever's implementing this has the time, throw in changes to check_initialized_ata to 1) be renamed to check_ata_initialized and run check_ata within it so you don't have to run both
