fix: `_getBytes()` regex fails for large strings

[adraffy]

• simplify hex regex

[ricmoo]

Interesting. Is it the non-capturing matching group that causes it to fail or the matching group in general?

Can you provide an example string (or just a length) for which the function fails? And the environment (browser vs node)?

[adraffy]

Seems okay in node but:

$ bun --version
1.2.4
$ bun repl
> require('ethers').getBytes('0x'.padEnd(86014, '0'))
> require('ethers').getBytes('0x'.padEnd(86016, '0')) // error: invalid BytesLike value

It seems fixed now on 1.2.6?

It's still probably worth it to make the change:

• !!'0x'.padEnd(3000000, '0').match(/^0x(?:[0-9a-f][0-9a-f])*$/i) → false
• !!'0x'.padEnd(3000000, '0').match(/^0x[0-9a-f]*$/) → true
• !!'0x'.padEnd(1000000000, '0').match(/^0x[0-9a-f]*$/) → true

I encountered it parsing blobs.
