Hello, great work so far! Thanks for another great module :)

I tested with fromFile and fromStream and .lz4 and .avro files are not properly detected.

LZ4 Magic Number: 4 Bytes, Little endian format. Value : 0x184D2204 https://fuchsia.googlesource.com/third_party/lz4/+/HEAD/doc/lz4_Frame_format.md

AVRO Magic Number: Four bytes, ASCII 'O', 'b', 'j', followed by 1 http://avro.apache.org/docs/current/spec.html#Object+Container+Files

just tested on 7-zip, its lz4s start with 502a 4d18 instead of 0422 4d18

I've opened up a PR for the avro file type support: https://github.com/sindresorhus/file-type/pull/597
