add: fpm search

[henilp105]

This PR intends to add the search and discovery of fpm installed and fpm - registry packages directly from cli. this command supports globbing for package name, version, license, namespace. the similar functionality has been patched at the registry repo. (fortran-lang/registry#81). paging is not used in local registry due to multiple search queries.

This is the syntax of the new fpm search functionality:

fpm search --query q* --page 1 --registry URL --namespace n* --package p* --package_version v* --license l* --limit 10 --sort-by [name] --sort [asc/desc]

Parameters:

• query: Searches in fpm.toml description and fpm-registry descriptions only for fpm-registry (README.md) (case insensitive, globbing supported).
• package: Searches by package name (case insensitive, globbing supported).
• registry: Custom registry URL (default: fpm-registry).
• namespace: Searches by namespace (globbing supported).
• package_version: Searches by package version (globbing supported).
• license: Searches by license (globbing supported).
• page: Page number (default: 1).
• limit: Number of results (default: 10).
• sort-by: Sorts by name, author, createdat, updatedat, downloads (default: name).
• sort: Order of sorting, asc or desc (default: asc).

Tasks left

• add docs and tests
• clean and refactor

Thanks and Regards,
Henil
