chore: fix generated file and class names

[camsjams]

Fixes #292

Previous version of normalizeName from TypeChain: https://github.com/dethcrypto/TypeChain/blob/2fcc74371ed0c2c587fb87e9ce0faa935e22942a/packages/typechain/src/parser/normalizeName.ts

Recently updated version of normalizeName from TypeChain: https://github.com/dethcrypto/TypeChain/blob/3a8a99ad4641af8a4dae498566ccd837e15d7034/packages/typechain/src/parser/normalizeName.ts

Luckily there was a copy already inside the fuels-ts repo

I'm testing it using swayswap and because the name of the file has the underscore, looks like the normalizeName didn't try to improve the name and just use it.

I just write a custom normalizeName and tested locally this one should work better for us;

function normalizeName(rawName: string): string {
  const transformations: ((s: string) => string)[] = [
    (s) => s.replace(/_/g, '-'), // replace "_" to '-'
    (s) => s.replace(/\s+/g, '-'), // spaces to - so later we can automatically convert them
    (s) => s.replace(/\./g, '-'), // replace "."
    (s) => s.replace(/-[a-z]/g, (match) => match.slice(-1).toUpperCase()), // delete '-' and capitalize the letter after them
    (s) => s.replace(/-/g, ''), // delete any '-' left
    (s) => s.replace(/^\d+/, ''), // removes leading digits
    (s) => s.replace(/[a-z]/, (match) => match.slice(-1).toUpperCase()), // upper case first letter
  ];

  const finalName = transformations.reduce((s, t) => t(s), rawName);

  if (finalName === '') {
    throw new Error(`Can't guess class name, please rename file: ${rawName}`);
  }

  return finalName;
}

@luizstacio I've added some tests, I linked my local Swap Swap to this typechain-target-fuels and it worked, it reverted the names back to how they were previous to TypeChain v8+

Nice!
