Apache arrow input

[alippai]

Apache Arrow is an aligned chunked array representation of columns. If my matrix is a dense matrix encoded as a chunked array of float64 numbers is it possible to use faer-rs on top of it in a zero-copy way? I assume further constraints (chunksize has to be a multiple of some batch size) will be required. Or will we have to combine the (relatively large) chunks into a continuous aligned array first before feeding it to faer?
