4186d117af Replace OpenOptions::new with File::options to be readable (#3059)
## Issue Addressed

Closes #3049 

This PR updates widely but this replace is safe as `File::options()` is equivelent to `OpenOptions::new()`.

c5e97b9bf7 Add validation to kdf parameters (#1930)
## Issue Addressed

Closes #1906 
Closes #1907 

## Proposed Changes

- Emits warnings when the KDF parameters are two low.
- Returns errors when the KDF parameters are high enough to pose a potential DoS threat.
- Validates AES IV length is 128 bits, errors if empty, warnings otherwise.

## Additional Info

NIST advice used for PBKDF2 ranges https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication800-132.pdf. 
Scrypt ranges are based on the maximum value of the `u32` (i.e 4GB of memory)

The minimum range has been set to anything below the default fields.

3db9072fee Reject invalid utf-8 characters during encryption (#1928)
## Issue Addressed

Closes #1889 

## Proposed Changes

- Error when passwords which use invalid UTF-8 characters during encryption. 
- Add some tests

## Additional Info

I've decided to error when bad characters are used to create/encrypt a keystore but think we should allow them during decryption since either the keystore was created
-  with invalid UTF-8 characters (possibly by another client or someone whose password is random bytes) in which case we'd want them to be able to decrypt their keystore using the right key.
-  without invalid characters then the password checksum would almost certainly fail.

Happy to add them to decryption if we want to make the decryption more trigger happy 😋 , it would only be a one line change and would tell the user which character index is causing the issue.
