feat: Add a Method to Support Dynamic Element Sizes in Sequence

[tareknaser]

Rationale for this change

So far, all the methods to create a Sequence seem to be on statically sized types.

What changes are included in this PR?

Implement from_raw_parts_with_size() for handling variable-sized elements.

Are these changes tested?

Yes. Added a test we_can_convert_a_slice_of_fixed_size_binary_to_a_sequence_with_correct_data() to verify the changes

Sorry for the delay on this. @jacobtrombetta would be good to get your input here.

We should update the from_raw_parts method to use from_raw_parts_with_size.

pub fn from_raw_parts<T>(slice: &'a [T], is_signed: bool) -> Self {
   let element_size = core::mem::size_of::<T>();
   Self::from_raw_parts_with_size(slice, element_size, is_signed)
} 

This will allow us to minimize duplicate code.

Thanks for the review. I’ve updated the PR to address your comments and rebased it on top of main. Let me know if there’s anything else
