The project source is incomplete.

Hi
Thanks to that, we are developing easily.
But when I try to build it with the latest source, I get an error.

In the KeyTools.cs file in the Crypto folder of the LaksaCsharp project
No class associated with Numeric.
(Numeric.ToHexStringNoPrefixZeroPadded, Numeric.HexStringToByteArray)

Then, when the sign operation is performed in the transaction operation sample source, the Exception is returned from the Validation.IsBech32 check.
The recipient address is 4baf5fada8e5db92c3d3242618c5b47133ae003c.

Please confirm. Thank you.
