Prerelease String shouldn't always be treated as lower version

[Maimonator]

Hey,
I've found some irregularity where I have the following two versions for tcpdump
4.9.3-4ubuntu0.1
4.9.3

Using the example code from the readme we get that 4.9.3 is greater than 4.9.3-4ubuntu0.1 even though that's not the case
Link to playground to see my tests.

I'm pretty sure that 4ubuntu0.1 doesn't mean it's a prerelease version and it's a widely used suffix.
In other compiled binaries for ubuntu.

I'm not sure what's the correct approach to solve this, but I was wondering whether we should narrow down the behavior when evaluating the prerelease string.
WDYT?
