fix: Fixes file reading. (#958)

Browse source 
.NET 6 introduced a breaking change where lseek and sys-calls are not used for reading and file streams. This effectively broke out native reader. Since the file reading is fairly optimized, and honestly we don't need it to be "fast" in this case, I have removed the native reader.
