*
* The `mode` string is treated roughly the same as in a call to the C

*
* Available `mode` strings:
*
* - "r": Open a file for reading. The file must exist.
* - "w": Create an empty file for writing. If a file with the same name
* already exists its content is erased and the file is treated as a new

* - "w+": Create an empty file for both reading and writing. If a file with
* the same name already exists its content is erased and the file is

* overwritten. You can reposition (fseek, rewind) the internal pointer to
* anywhere in the file for reading, but writing operations will move it
* back to the end of file. The file is created if it does not exist.
*
* **NOTE**: In order to open a file as a binary file, a "b" character has to
* be included in the `mode` string. This additional "b" character can either
* be appended at the end of the string (thus making the following compound
* modes: "rb", "wb", "ab", "r+b", "w+b", "a+b") or be inserted between the
* letter and the "+" sign for the mixed modes ("rb+", "wb+", "ab+").
* Additional characters may follow the sequence, although they should have no
* effect. For example, "t" is sometimes appended to make explicit the file is
* a text file.
*
