Fix GenericPrecompileRegistry

[therealbytes]

Rationale

This is a crucial part of Concrete and the implementation is a bit of a mess right now.

Implementation

Fix the implementation of GenericPrecompileRegistry and test it properly.

Desired implementation:

// AddPrecompiles takes a mapping of precompiles and assigns it to a block.
// These precompiles will be considered to be active in all blocks between the assigned block (inclusive)
// and the next assigned block (exclusive).
AddPrecompiles(startingBlock uint64, precompiles map[common.Address]Precompile)
// AddPrecompile assigns a precompile to a block and address.
AddPrecompile(startingBlock uint64, address common.Address, precompile Precompile)
// Precompiles returns a mapping of all active precompiles in the given block.
Precompiles(blockNumber uint64) map[common.Address]Precompile
// Precompile returns the active precompile at the given block and address, if any, and true if there is one.
Precompile(address common.Address, blockNumber uint64) (Precompile, bool)
// Active precompiles should be removed. Precompiles should only return precompiles that are active.
ActivePrecompiles(blockNumber uint64) []common.Address

Hi @therealbytes , I would like to work on this task, I have experience in Golang and love to contribute this project.

I will add the missing methods in the PrecompileRegistry and add missing test cases for those methods as well.
will connect with you guys over Discord for more discussions if needed.
