Add scalar multiplication to BigUint, BigInt
...
BigUint and BigInt can now be multiplied by a BigDigit, re-using the same buffer for the output, thereby reducing allocations and copying.

BigInt two's complement adjustments
...
- rename `_twos_complement_` methods to just `_signed_`
- make `from_` variants take &[u8]
- refactor helper functions twos_complement (they take byte slice but use a generic function underneath)
- fix issues in `to_signed_` functions (only two's complement negative numbers; perform byte extension where needed)
- add tests to `to_signed_` methods

Add BigInt 2's complement conversions
...
- add methods `from_twos_complement_bytes_le`, `from_twos_complement_bytes_be`, `to_twos_complement_bytes_le`, and `to_twos_complement_bytes_be` to `BigInt`.
- add respective tests
