Array creation should take strings for filters, serializer, compressors

[d-v-b]

For a user who is happy to use crc32c and zstd with whatever the defaults happen to be, create_array(..., compressors=('crc32c', 'zstd')) is a lot more ergonomic than create_array(..., compressors=({'name': 'crc32c'}, {'name' : 'zstd'})). So we should accept the iterable of strings.
