[accumulator-updater 3/x] Update Inputs Ix (#741) 

* feat(accumulator_updater): initial skeleton for accumulator_udpater program

Initial layout for accumulator updater program. Includes mock-cpi-caller which is meant to represent
pyth oracle(or any future allowed program) that will call the accumulator updater program. All
implementation details are open for discussion/subject to change

* test(accumulator_updater): add additional checks in tests and minor clean up

* chore(accumulator_updater): misc clean-up

* refactor(accumulator_updater): added comments & to-dos and minor refactoring to address PR comments

* feat(accumulator_updater): nmanual serialization for mock-cpi-caller schemas & use zero-copy

* chore(accumulator-updater): misc clean-up

* refactor(accumulator-updater): rename parameter in accumulator-updater::initalize ix for consistency

* style(accumulator-updater): switch PriceAccountType enum variants to camelcase

* refactor(accumulator-updater): address PR comments

rename schema to message & associated price messages, remove unncessary
comments, changed addAllowedProgram to setAllowedPrograms

* refactor(accumulator-updater): address more PR comments

consolidate SetAllowedPrograms and UpdateWhitelistAuthority into one context

* style(accumulator-updater): minor style fixes to address PR comments

* feat(accumulator-updater): implement update-inputs ix, add bump to AccumulatorInput header

* feat(accumulator-updater): implement update ix

* refactor(accumulator-updater): refactor ixs & state into modules

* docs(accumulator-updater): add comments for ixs

* feat(accumulator-updater): consolidate add/update_inputs into emit_inputs ix (#743)

* refactor(accumulator-updater): clean up unused fn, rename fns

* fix(accumulator-updater): fix error from resolving merge conflicts

* refactor(accumulator_updater): address PR comments

Remove account_type, rename emit_inputs to put_all to be more similar to a Map interface, added
AccumulatorHeader::CURRENT_VERSION

* docs(accumulator_updater): add docs for AccumulatorInput struct
