Reconstruct a CompiledInstruction from various UiInstruction formats

This is required because when you simulate a transaction with inner instructions flag, the RPC pre-parses some of the instructions (like for SPL program and System Program), however this is an issue for Kora, as we expected “Compiled” instructions rather than “Parsed” instructions, because we have our own parsing logic on our Kora’s side.

So we need to reconstruct the “Compiled” instructions from the “Parsed” instructions, by “unparsing” the “Parsed” instructions.

There’s no known way to force the RPC to not parsed the instructions, so we need this “hack” to reverse the process.

Example: https://github.com/anza-xyz/agave/blob/68032b576dc4c14b31c15974c6734ae1513980a3/transaction-status/src/parse_system.rs#L11

pub fn parse_system_instructions( transaction: &VersionedTransactionResolved, ) -> Result<HashMap<ParsedSystemInstructionType, Vec<ParsedSystemInstructionData>>, KoraError>

pub fn parse_token_instructions( transaction: &VersionedTransactionResolved, ) -> Result<HashMap<ParsedSPLInstructionType, Vec<ParsedSPLInstructionData>>, KoraError>
