Tests for timelock - check lock time verify (CLTV) (#1751)
* Create a file

* Add tests for lockTime - CLTV scripts conditioned by time and block height

* Add a handle for an unhandled error.

* Renamed the test file

* Fix typo

* Add a counter for current block height.

* Change variable name

* Adds a test for wrong lock time, removed fundingTransaction variable

* Fix LockTimeThreshold constant, fix opcodeCheckLockTimeVerify and opcodeCheckSequenceVerify(padding in the end), add support for sequence and lock time number in the script builder, add more checks to the CLTV test.

* Call AddData instead of addData. Rename fixedSize to unpaddedSize

* Creating wrapper functions to lockTime&sequence numbers that call to a shared function in script builder.
