sort: change byte order for Big-endian

The radix sort variants need a byte-swapping to work on Big-endian architectures such as mips mips64 ppc64 s390x. (This is indicated by runtime/internal/sys.BigEndian, but don't use that value; use GOARCH build flags.)

Without one the sorting will work, and iterate as usual through fields, but within fields go from the most to least significant digit (byte). Adjustment values for negative fields will be off, though, as those are encoded in uint64.

Given a version, list possible next versions?

Thanks for this lib, Mark. I'm wondering if you'd entertain a discussion (even a brief one) about the possibility of a function that takes as input a semantic version and returns a list of (reasonable) possible next versions.

In other words, given this:

"v1.0.0"

The function might return:

[]string{"v1.0.1", "v1.1.0", "v2.0.0"}

And (optionally?) some pre-release "next" versions as well. I'm using this to prompt a user what to tag a commit as.

Would this function have a place in your lib?

How does this differ / compare to hashicorps go-version

Trying to understand when I would want to use this over theirs. https://github.com/hashicorp/go-version Not trying to start any religious war.

Export "version fields" accessors

It would be great if you could access a "version field" such as

v := semver.NewVersion("1.0.0")
fmt.Println(v.Major)
fmt.Println(v.Minor)
fmt.Println(v.Patch)

Can NewVersion() return a *Version?

I am wondering if you'd welcome a pull request to have NewVersion() return a *Version instead of a Version, mostly because all the methods are implemented with pointer receivers, so I can't easily make a NewVersion() and then call methods on them; I have to reference them every time, or re-assign the variable.

Currently:

current, err := semver.NewVersion("1.2.3")
fmt.Printf("%s\n", current) // formatting error
fmt.Printf("%s\n" &current) // works

Not a big deal, but could make my use of the returned value a little simpler in actual code, where I have to constantly reference it or re-assign the variable. It's also possible that I'm misusing the lib, just let me know if that's the case!
