fix: use non-capturing group in getBytes regexp

[doomsower]

While doing huge read request I encountered following error in my code:

RangeError: Maximum call stack size exceeded 
    at String.match (<anonymous>)
    at _getBytes (/app/node_modules/ethers/src.ts/utils/data.ts:34:45)
    at getBytes (/app/node_modules/ethers/src.ts/utils/data.ts:55:12)
    at hexlify (/app/node_modules/ethers/src.ts/utils/data.ts:102:19)
    at JsonRpcProvider.#call (/app/node_modules/ethers/src.ts/providers/abstract-provider.ts:974:28)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

With some insight from this post here I changed regexp to use non-capturing group, and that fixed my app.

Good idea! I'll get this into the next patch release.

Thanks! :)

Added in v6.12.2. Let me know if you come across any other regex's that make sense to non-capture. ;)

Thanks!
