* Add offset curve
* Fix for math
* Add PreciseNumber
* Use Balancer formulation for trading token -> pool token conversion
* Add round-trip conversion testing
* Add offset curve to JS

This encompasses a lot of changes to properly support the constant price
curve, and fixes some old pain points to make the whole thing easier to
use, including:
* refactor fees out of the curve

* Added stable curve invariant to the token swap smart contract
* Fixed formatting
* Added missing stable curve constraints
* Symbol renames to make math clearer
* Small refactoring according to PR comments, fixes for JS tests
* Add mints to swap info

* Add fee account in SwapInfo / init
* Add test for 0 fee, init test fully
* Add withdraw command interface
* Add fee accounts to swap instruction
* Add calculations for swap and withdraw fees
* Run cargo fmt
* Add new fees to JS and test
* Review feedback: fixup instruction doc and clone
* Update order of accounts in instructions
* Run cargo fmt
* Fix owner fee pool token calculation to include trading fee
* Add owner fees to flat curve, per request
* Fix instruction comment numbering
* Add more errors types for clearer calculation errors
Add a check for withdrawing from fee account

* token-swap: Add token supply in invariant calculation
* Refactor state classes into curve components for future use
* Align pool initialization with Uniswap using geometric mean of token
amounts
* Fix deposit and withdraw instruction to work as a proportion of pool
tokens
* Add math utilities to calculate the geometric mean with u64
* Improve variable names
* Use a fixed starting pool size
* Run cargo fmt
* Update js tests with new pool numbers
* Run linting
* Remove math
* Fix BN type issues found by flow
* Fix lint check in CI
* `npm run lint` now checks that code is properly formatted, instead of
running the formatter
* Add extra commands to run the linting, include ts definitions file
* Update flow-bin, fix type errors that come up
* Clarify lint vs lint:fix as requested
* Run `pretty` properly
* Add `build:program` like for spl-token
* Add TypeScript to CI
* snake_case -> camelCase variables
* Combine transactions on swap initialization
* Make instruction functions static
* Pack instructions and state more efficiently
* SwapInfo and SwapInstruction are more memory-efficient, following the
example from SPL Token
* Remove unnecessary helper structs to make instructions clearer
* Error -> SwapError
* Update JS tests to reflect the change
* Integrate review feedback
* Fix local token-swap tests
* Change generation of program address to use a nonce
* Accept nonce properly in initialization
* Include nonce in TokenSwap structure
* Fixup serialization with new parameter (padding used for now)
* Update dependencies
Update toml / lock files
Fix token swap initialization end-to-end
Cleanup unit test to use `find_program_address`
Add / refactor tests
Most importantly, added a special test to make sure that
token_program_id is provided at the end of CPI instructions, since
unit testing did not pick up that problem, and it was tough to debug
during end-to-end testing
* Revert some testing changes for PR
* Update token-swap/program/src/processor.rs
