Added support for generating Latvian id number

[cbxp]

• We support two formats: old (before 01.07.2017) and new (since 01.07.2017)
• For generating invalid ID numbers, we use only the old format (for simplicity)

PR Summary

• Creation of a New Class for Latvian Identification Numbers
  This update includes the creation of a new class known as LatvianIdNumber. Its specific role is to generate valid and, if needed, invalid Latvian identification numbers, enhancing the flexibility of our system.

• Introduction of Valid Identification Number Generation Methods
  We've implemented advanced methods able to generate valid identification numbers based on key parameters such as date of birth and gender. The new methods are designed to accurately distinguish between old and new ID formats, ensuring up-to-date compatibility.

• Inclusion of Checksum Calculation
  To further fortify our system's ID validation process, we've added a checksum computation to the ID numbers to verify their integrity according to the mandated format.

• Service File Adjusted to Support New Class
  Our service file has been promptly updated to incorporate the LatvianIdNumber in the roster of ID number generators, bolstering the available options for users.

• Development of Unit Tests for Latvian Identification Numbers
  Critical to ensuring the seamless operation of this new feature, we've developed corresponding unit tests denoted as LatvianIdNumberTest. These tests validate the checksum calculations and confirm the ID number format conforms to both old and new versions.

• Expansion of Existing Tests
  Going beyond the new feature, we've also intensified our existing testing suite in IdNumberTest. This fortified suite now encompasses additional tests for both valid and invalid Latvian ID numbers, thus enhancing our system’s overall functionality and precision.

nit: i guess in case of year 1700 it will fail with Too far in future: 1700 which doesn't sound like true
may be something like out of allowed range [1800, 2100) would fit better

Thanks, error message improved.
