Coerce from right-to-left

[marceloavf]

By default, coerce runs from left-to-right returning the version, I would discuss if it should be possible to have an option to check from right-to-left.

Actual example:

semver.coerce('test/v1.0.0/app-v1.2.3-install.exe')
//=> version: "1.0.0"

Possibility

semver.coerce('test/v1.0.0/app-v1.2.3-install.exe', 'right-to-left')
//=> version: "1.2.3"

I'd avoid a magic string in the API, and we already accept an options object as the second argument. How about coerce(string, { rtl: true })?

Would be nice @isaacs

Landed on 6.2.0. Turned out to be an interesting little algorithm! You don't want 1.2.3.4 to coerce to 4.0.0 in rtl mode. I'd expect 2.3.4 in that case. I think what I landed on is reasonably efficient and does the right thing.
