✨ Exclude Prereleases from Exclusive Matching

[JustinGrote]

Modifies behavior so that Module<2.0 does not match 2.0.0-alpha1 unless -StrictSemVer is specified
Fixes #107

@Jaykul can you please review and comment. Main concerns:

• Since the -StrictSemVer is command wide, there's no way to specify some things you want strict and some you didn't. Maybe we need to add new spec syntax such as "!!" or something as well. Probably not worth the effort unless someone complains
• I expanded the definition beyond major versions, so for instance Module<3.2.1 will exclude 3.2.1-alpha1, using the same logic as what we discussed. Let me know if you see any issues with that.
