fix: signature verification

[shotonoff]

Issue being fixed or feature implemented

Tenderdash uses ThresholdVerify function (that is binding to bls::Threshold::Verify) to verify the signature of the message digest that doesn't compatible with core

What was done?

• Use BasicSchemeMPL for signing and verifying operations
• Replaced bls::Threshold::Verify on BasicSchemaMPL.Verify to be able to verify core's signature
• Updated the version of BLS module (1.2.6)

How Has This Been Tested?
