feat: Support Wildcard and * contract filters

[Kevin101Zhang]

added the * filter for contracts.
A valid contract is defined as

function validateContractId(accountId) {
  accountId = accountId.trim();
  
  const isLengthValid = accountId.length >= 2 && accountId.length <= 64;
  if (!isLengthValid) return false; 

  //test if the string starts with a '*.' and remove it if it does
  const isWildCard = WILD_CARD_REGEX.test(accountId);
  isWildCard ? accountId = accountId.slice(2) : null;

  //test if rest of string is valid accounting for/not isWildCard
  const isRegexValid = CONTRACT_NAME_REGEX.test(accountId);
  return isRegexValid;
}

note: early termination for performance

The function take in account all invalid contract names on nomicon
Please view test for more details.

Regex Broken down Below:

CONTRACT_NAME_REGEX:

/^(([a-z\d]+[-_])*[a-z\d]+(\.([a-z\d]+[-_])*[a-z\d]+)*\.([a-z\d]+)|([a-z\d]+))$/

1. ^: Asserts the start of the string.

2. (: Begins a capturing group.

3. ([a-z\d]+[-_])*: Matches a sequence of lowercase letters or digits, possibly followed by hyphens or underscores. The sequence may repeat zero or more times.

4. [a-z\d]+: Matches a sequence of one or more lowercase letters or digits.

5. (.([a-z\d]+[-_])[a-z\d]+): Allows for zero or more occurrences of a dot . followed by another sequence.

6. .([a-z\d]+): Matches a dot followed by a sequence of lowercase letters or digits.

7. |: OR operator.

8. ([a-z\d]+): Matches a standalone sequence of lowercase letters or digits.

9. )$: Asserts the end of the string.
   WILD_CARD_REGEX:

/\*\./

1. *: Matches a literal asterisk.
2. .: Matches a literal dot.

EDIT: Added more test please review
Added jest to support function testing.

It seems there's a problem getting Babel and the VM to work smoothly together. I'm going to dig deeper into it. Right now, I'm adjusting the test file to recreate the functions instead of using the usual require/import method, which seems to cause trouble with the VM code. It does mean there's some duplicated code in the testing files, but the test work.

Some comments on the updated regex, and testing methodology. Great job adding jest here!

Mostly looks good to me.

I just want to clarify once more that we want to support* as that seems correct to me. I checked with Pavel and he confirmed what I thought about supporting * alone.

Also dropped a suggestion for fixing that babel issue. If it works, awesome. If not, no big deal, we can defer it. Leave a TODO in the test file to replace with imports later.

Nice job on the regex!

[darunrs]

Looks good to me. There's a merge conflict but otherwise, should be good.

Add a comment above the original validate functions that they're duplicated in the test files due to a Babel config issue, and a TODO to address that.

Also, can you rename the PR to something like feat: Support Wildcard and * contract filters?
