### Summary
This PR introduces a new class `LongBitField` that extends the concept of
`BitField` to support 64-bit values (`long`).
The existing `BitField` only supports `int`, `short` and `byte`, which is
insufficient for modern use cases involving large flags or 64-bit bitsets.
### Features
- Supports all basic bit operations: `set`, `clear`, `setBoolean`,
`getValue`, `getRawValue`, `isSet`, `isAllSet`.
- Operates on `long` values to allow 64-bit flags.
- Fully unit-tested in `LongBitFieldTest.java`, covering:
-> Single-bit and multi-bit masks
-> Edge cases (lowest and highest bits)
-> Boolean set/clear operations
-> Setting and getting values
- Designed to be consistent with `BitField` API for easy adoption.
### Motivation
- 'BitField' is limited to 32-bit integers (`int`). Many modern applications
require 64-bit flags or large bitsets.
- This class provides a direct, intuitive solution for such cases without
needing to manually manipulate `long` values.
### Testing
- All methods are covered by JUnit tests in `LongBitFieldTest.java`.
- Tests validate correctness of all bit operations, including edge cases.
- Tests can be run using standard Maven/Gradle build for Apache Commons Lang.
