Started by doing a SchemaEngine but at the end I just put everything
inside the FileEngine.
Now you can use 'schema init path/to/schema' to initialize the struct
folders and first data file, Also save a copy of the schema in a file in
the ZipponDB folder.
Created a new folder to clean a bit the repo, put the file and schema
engine inside. As those and Parser depend on the types.zig, I also add
this folder inside the new engines folder
Created a new Parser unique for the FileEngine to read each line.
It is slower as I need to parser character by character because their is
no fixed len for the data in files. Before I was just reading until the
end of the file.
Im gonna need to find some tricks to improve the parsing of data. I am
thinking using the stream directly instead of doing streamUntilDelimiter
