Solana IDL Spec

Standardizing a Solana IDL Standard, originally built by Coral's Anchor Framework.

Goals of Standardizing the IDL

1. Increase composability across the Solana ecosystem
2. Allow developer tools other than Anchor to target the IDL

Requested Updates

1. Explicit instruction discriminators
2. Explicit account discriminators
3. A list of standardized types (Array/Vec, Solana Pubkey, etc)
4. Serialization format (borsh, bincode, etc)
5. Security information
6. A typed "metadata" object
