This makes these two data types more lightweight, requiring only two memory allocations (one for the sequence and one for its memory) as opposed to two. It also improves data locality since loading from the sequences won't require a double load through the indirection of `Vector`. The disadvanges are twofold: First, we lose support for Julia 1.10 since Memory was introduced in Julia 1.11 Second, Vector's code to grow its underlying memory is much more optimised and tested than the manual implementation here in BioSequences. This would matter if users did a lot of resizing operations on biosequences, like `push!` or so. However, I think they don't - they are instead much more likely to create a lot of sequences. If necessary, we can always implement better resizing / growth behaviour for these types.
