Does this library support not aligned buffers?

I am using the `AES_CTR_xcrypt_buffer(&tx, chunk_data, chunk_len)` method on a microcontroller with an `lwip` stack, from which data are not 4-bytes aligned.

Can this library handle this?

Start by inspecting the AES_CTR_xcrypt_buffer implementation for assumptions about buffer alignment and reviewing how lwip supplies chunk_data. Determine whether unaligned buffers are supported, and document or reproduce the result with a focused test if the repository has relevant test coverage.
