* test: showing that tuple types are parsed as None

* tuples: adding two element tuple support up to IDL generation

Next step is to allow more elements in a tuple which will be a bigger
change and thus isn't included here

* chore: composite types now have dynamic amount of inner types

* idl: full support for dynamic els tuples

* chore: finish parser level tuple tests

* extend shank instructions to have more than one field

* parse multiple instruction fields

* add test examples

* chore: rename instructionArg(s) to arg(s)

- they are inside an instruction thus that context is already provided
- shorter names result in better generated code with solita

- turns out this is an experimental feature

* parse coption as a normal option type

* add -p argument for overriding program address

* address naming & error nits

* rust fmt

* remove COption parsing until confirmed

* chore: consistent program_address_override naming

* test: add hash/btree set integration test

* feat: support hash/btree sets

* ix: parsing out instruction strategy attribute (default_optional_accounts)

* macro: adding default_optional_accounts attribute

* macro: store strategies in hashset

- only one instance of a particular strategy makes sense per instruction

* idl: integrate strategy as boolean in instruction and added tests

Fix: module collision
