Transfer ECOV via ecoswap program

[irene-bbox]

Description

Transfer an spl-token (ECOV) via a unified Rust program which orchestrates both the transfer of SOL & the transfer of ECOV concurrently.

Tasks

• user the .ts client to feed the right PDA to the Rust program
• hard code into the Rust program the correct seed (only the seed is enough - no bump)
• re-create the PDA inside the Rust program from seed
• ensure the program callers are authorized callers
• multiply amount of SOL by 10E-9 to convert from SOL Lamports to ECOV units
• send right amount of ECOV to whomever got deducted of SOL
