TODO

SHORT-TERM
- create Address object that covers all addresses and can convert from one to another
- taproot's op_addchecksig simply added
  . other tapscript changes?
  . think: how to differentiate tapscript in code? (right now addchecksig can be used in any script)

Transaction-related
- think how to add/remove existing inputs/outputs to a Tx object
  . will need to add add_input/output (same as append)
  . allow to update an input/output from any index
  . allow to remove an input/output altogether
  . influences set_witness (add_input should add the empty witness immediately?)

SEGWIT-related
- segwit v0 and v1 address object instantiates from address, witness program and script
  . are all used? test?
- add annex to signature hash (easy, just add in bytes or hex in the method and include)

CLEAN UP 
- segwit examples and get_transaction_segwit_digest 

TYPING 
- use stubs for mypy to get type hints for external libraries that don't support hints (for now using # type: ignore for external libs)
- python.analysis.useLibraryCodeForTypes is set to false for pyright to not auto-deduce types for external libraries that do not use hint stubs / mypy)

IMPROVE
- test proxy object extensively, students reports it fails sometimes
- make a new proxy object from scratch (test with at least 2/3 of bitcoin core RPC)

DOC-related
- create jupyter notebooks?

tests-related
- improve test structure - similar to Bitcoin core 

OTHER
- create script: clean-less-than-sats 100000 bc1q86gsg4t32...
- maybe make RBF the default from now on (like Bitcoin Core)
  . will need to change all the tests, unless I add minor hack that uses RBF by default only for taproot
