Allow slice types to be pushed and lift Windows restriction

[kojofl]

This PR aims to introduce two changes:

1. Increase API Flexibility: Functions that previously required a &Vec<T> have been generalized to accept any type that can be referenced as a slice (e.g., &[T], Vec<T>, &[T; N]). This is a non-breaking change.
2. Address TODO: Allow the push of i64 samples on windows as mentioned in the TODO since the crate now depends on liblsl 1.16.2
