To update solana-bankrun

Points on how to work with solana-bankrun, to update the code and then test it in a project on local computer.

Update solana-bankrun

As of the PR kevinheavey/solana-bankrun#31 the change consists of update of src/lib.rs to update linking to solana program test: https://github.com/anza-xyz/agave/blob/v2.0.9/program-test/src/lib.rs#L1016

From changes in src/lib.rs the linking to TypeScript is needed to be coded into index.ts.

I used to have a site bookmarked with a table of all these functions, but the link is dead. Here's a matrix of Option and Result conversion functions. These become second nature once you have used Rust for any significant length of time, but it's useful to have a table reference.

For each of the below:

• T is the value possibly contained in an input Ok Result or Some Option.
• U is a new value created by transforming or replacing an input T. Note that when U appears in methods like map, U ?= T, for example by calling

    let data: &mut [u8] = &mut [0, 0, 0, 0]; // your byte slice
    let index: usize = 2; // the position where you want to write the byte
    let byte: u8 = 42; // the byte you want to write; 42 => 
    
    // Write the byte to the specified position in the byte slice
    data[index] = byte;
    
    print_byte(&byte);
