add support for fixed size array of any type

[MarioProjects]

@ailisp @defactojob or @mehtaphysical there is any update?

I want to send a list of [u64; 12] (96 bytes) but I cannot achieve it with this code:

let parsed_bundles = bundles.split(";").map(Number);
let bundles_prices = [];
for (let i = 0; i < 12; i++) {
    bundles_prices.push(new BN(sol_to_lamports(parsed_bundles[i]), 16) || new BN(0, 16));
}

Error: Expecting byte array of length 96, but got 12 bytes

Any suggestion or help? Thanks!

When you say of any type, does that include f64?
