libphonenumber-geo-carrier's Issues

Czech carriers

Hello,
your project has issues decoding Czech phone numbers

const main2 = async () => {
  const mobileNumber = parsePhoneNumberFromString('[phone]')
  console.log(mobileNumber.formatInternational()); // [phone]
  const carrierEN = await carrier(mobileNumber) // T-Mobile
  console.log(carrierEN);
  
  console.log('-------------------------');
  
  const mobileNumber2 = parsePhoneNumberFromString('[phone]')
  console.log(mobileNumber2.formatInternational()); // [phone]
  const carrierEN2 = await carrier(mobileNumber2) // null, should also be T-Mobile
  console.log(carrierEN2);
}

main2();

The issue seems to be in getPrefix, that returns 3 digits (605 or 779 in above cases), the problem is, that the bson is defined as

{
  '605': 'T-Mobile',
  '77999': 'T-Mobile',
  ... and bunch of others 
}

the prefix checking should not be based on international phone number format

Returns all US timeszones?

I may be doing something wrong, but in all my tests so far, trying to determine the timezone of a US number seems to return every US timezone (or at least a lot, most of which don't make sense).

Take for example the number of the Sacramento Zoo, [phone]

const number = parsePhoneNumber('[phone]')
const tzs = await timezones(number)
/* tzs equals:
