Add support for the 8-byte long timestamp delta encoding

[LinZhihao-723]

Description

The current IR encoding protocol doesn't support 8-byte timestamp delta encoding. This means the current four-byte encoding IR stream cannot contain a timestamp delta of more than +/- 24.86 days. This PR resolves this problem by introducing an 8-byte timestamp delta encoding.
The protocol version number is bumped to "v0.0.1". As a result, the version of the decoder must have been up-to-date to decode an 8-byte encoded timestamp delta properly.
To validate the version, a validation function is added to check whether the built protocol version number is greater or equal to the input protocol version number. The current version validation relies on the SemVar https://semver.org/#backusnaur-form-grammar-for-valid-semver-versions convention.

Validation performed

• Added unit tests to cover the timestamp delta encoding for all integer sizes we support. Negative timestamp deltas are also tested.
• Tested the version number validation:
  • Ensured the old version (v0.0.0) can be compressed successfully.
  • Ensured the version that doesn't follow the SemVer convention will be caught.

Generally we should try to do unrelated formatting changes in another PR so that the changes in this PR concisely match their purpose, but it's not worth changing things back for this one.
