compress: add a deflate compressor

Replaces the inflate API from `inflateStream(reader: anytype, window_slice: []u8)` to
`decompressor(allocator: mem.Allocator, reader: anytype, dictionary: ?[]const u8)` and
`compressor(allocator: mem.Allocator, writer: anytype, level: Compression, dictionary: ?[]const u8)`
