fpm-ize the Fortran ecosystem

This proposal describes the plan and research I have done to make the packages in Fortran Ecosystem FPM compatible. I have described in detail how I am going to take the help of Fortran Community on Discourse for helping me in decision making and the metrics on which I will prioritize which packages to make compatible with fpm first. I have also put forward in detail the packages that I have researched on Github, Gitlab and other code hosting platforms that interest me and that I think should be made fpm compatible by looking at what we currently have in Fpm Registry. So, for this, I have also created a tentative timeline with a brief overview of my plan during the pre-GSoC, Community Bonding, and Coding Period. It also describes in detail my commitment to the program and my programming background as well. Goals of Projects : 1. Made packages from different domains like Command-Line Parsing, General Purpose Libraries, Command Line Parsing, and much more compatible with Fortran Package Manager. 2. Collaborate with maintainers of the packages which are to be made available on the fpm registry. 3. Interact with Fortran's open source community on Discourse and ask for suggestions and feedback while working on the project.
