Implemented the HIGHT block cipher with ECB mode support, including HightAlgorithm, HightCore, and HightEcbTransform classes. Updated the test program to include HIGHT encryption/decryption tests and added support for PaddingMode.None in ARIA and SEED ECB transforms.
Introduced a new test project 'WelsonJS.Cryptography.Test' with a Program.vb that tests SEED encryption and decryption. Updated the solution file to include both the cryptography library and its test project, and configured build settings for all platforms.
