fix: Fixes an issue with strings that starts with numbers

[cenavarro]

Hi,

When using PDF417.encode or PDF417.encode_to_base64 with a string that starts with a number and is greater than 13 digits, the NumberCompactor.compactable? is returning true due to Integer.parse(part) returning an output like {number, rest of string}

i.e a string like 74cLlWZPjVWX02 when calling Integer.parse("74cLlWZPjVWX02") it returns {74, "cLlWZPjVWX02"} and then later when using String.to_integer() in the def compact(part) function, it raises an error 1st argument: not a textual representation of an integer because it is not a string integer representation.

Instead of using Integer.parse, we can use a regex to only accept strings with numbers (string integer representation)

This is a good catch! Let me see if I can get the CI working, you might need to rebase that once it's up.

CI should work if you rebase on main now, and then we can get this merged and released. Thanks again!

Hi @photomattmills,

I rebased the main branch and pushed the changes again.
