What does this PR do?

Remove the lz4_flex crate from the dependencies and update test to use uncompressed file

Motivation

We removed lz4 in favour of zstd, but I saw an lz4 crate being compiled every time I build dd-trace-php and we should not compile stuff we don't need anymore.

Additional Notes

Anything else we should know when reviewing?

How to test the change?

cargo test
