No script validation when perform staking tx creation

[jrwbabylonlab]

All exposed functions like: (stakingTransaction)https://github.com/babylonlabs-io/btc-staking-ts/blob/dev/src/index.ts#L55
take already build scripts as arguments, without validating them. This leaves possibility for
errors for people using the library.
For example they need to remember to check that all keys in our scripts are unique etc.
It would be safer if our api operated on public keys or objects containing public keys.
