FR: Auto convert overly restrictive stdlib compat entries

[IanButterworth]

The original stdlib compat PSA suggested adding compat entries for stdlibs that are overly restrictive.

We should get CompatHelper to automatically change

[compat]
 StdlibName = "1"

to

[compat]
 StdlibName = "<0.0.1,1"

And if the StdlibName is "SHA", then we should auto-change it to < 0.0.1, 0.7, 1 instead.
