+Github cmdlets:
+- pass name of github repository
+- lists matching release versions (new/all/selected), with support for filters, automatically parses version (e.g. stripping out "v" prefix?)
+- retrieves download URLs (using a regex like '.*windows.*\.exe'? figure out how to support multiple resources, e.g. Alacritty)
+- has parameters indicating how to retrieve the hash:
+ - download the file and calculate the hash
+ - scriptblock that returns the URL of a checksums.txt or a similar file
+ - custom scriptblock that receives hashtable of Version/Url and returns the hash (e.g. custom checksum file format,
+   copying hash from another package manager repo,...)
