So far in each request to search or categories all manifest had to be reread from disk each time. As the packages do not change during the runtime of the service, this is not necessary and all can be cached on startup of the service and kept in memory. Even if there are one day 10000 packages and each manifest is 1KB, this would only consume ~10MB of memory (currently manifest are only about 250 Bytes). Using 10MB of memory instead of 10000 file read on each request seems worth it. The code was also modified to in general pass a copy of the packages instead of using a reference. This makes sure even if a request modifies the packages locally, the global package list is not modified.
remove requirement to use reference for IsNewer. Not needed simplify magefile by introducing also GetPackages make getPackagePaths private
