String to number conversion (stdlib)

This project will enhance stdlib’s string handling capabilities for fast number parsing in Fortran.

Recently, a new module was added to stdlib called stdlib_str2num which implements fast routines for converting strings to numerical types. The participant would get familiar with these implementations and subsequently:

• Create a full benchmark suite for the string to number conversion, across compiler vendors, operating systems, and CPU architectures.
• Explore ways to improve robustness and efficiency, e.g. error handling.
• Propose a shallow interface for the string_type facility in stdlib.
• Propose an enhancement to the loadtxt facility function to speed-up file reading.
• Depending on the advancement, the participant is also encouraged to include a roadmap for inclusion of the inverse conversion by following the initiative in this thread ryu-based to_string function

Relevant thread on Fortran Discrouse: Faster string to double

Expected outcomes: Enhancement of stdlib fast string to number conversion

Skills preferred: Fortran and C programming, understanding of floating-point arithmetic

Difficulty: intermediate, 175 hours

(@Carltoffel @everythingfunctional @ivanpribec you were listed in the previous proposal, do you want to stay in the list?)
@milancurcic (I added the shallow interface for string_type following your comment in the PR)
