Updating dependency to eliminate deprecation warning

[snake14]

Description:

Updating dependency to eliminate deprecation warning. The old dependency is no longer supported, so we had to switch to a fork which supports PHP 8.0.

Fixes: #164

Review

• Functional review done
• Potential edge cases thought about (behavior of the code with strange input, with strange internal state or possible interactions with other Matomo subsystems)
• Usability review done (is anything maybe unclear or think about anything that would cause people to reach out to support)
• Security review done
• Wording review done
• Code review done
• Tests were added if useful/possible
• Reviewed for breaking changes
• Developer changelog updated if needed
• Documentation added if needed
• Existing documentation updated if needed

This eliminates the deprecation error, but it doesn't support PHP 7.2. We might have to try a different library or use rector to downgrade. What do you think @AltamashShaikh ?

@snake14 We should try with Rector once and take a decision accordingly.
