SemVer parsing about semver

[antonkomarev]

I think that constructor should accept only versions of 100% correct format, but there could be an extra method which will try to make a guess.

$version = \PHLAK\SemVer\Version::parse('1.0');

Added in v3.2.0

I'm not sure how I feel about this.

• If the class is initialized with a version of 1.0 would the library handle it as 1.0 or 1.0.0?
• If the minor version is incremented would the version now be 1.1 or 1.1.0?
• If the major version is incremented would the version new version be 2.0 or 2.0.0?

I think if it's SemVer - it should have 3 digits delimited with points. If 1.0 passed - it should be instantiated as 1.0.0, and then minor version increment will be 1.1.0 and major version increment will be 2.0.0.

Maybe there should be an option to make the patch number optional. It's common to hide the patch number if it's zero.
