Bug#901531: p-try could be embedded in node-p-limit

[Paolo Greppi <paolo.greppi@libpf.com>]

Hi, this is a one-liner:
https://github.com/sindresorhus/p-try/blob/master/index.js#L4
so it could be embedded, see:
https://wiki.debian.org/Javascript/GroupSourcesTutorial

It is required to update p-limit to 2.0.0 
... which is required for node-p-locate 3.0.0 
... which is required for node-locate-path 3.0.0
so it could be embedded in p-limit and exported, as it has several dependents:
https://www.npmjs.com/package/p-try?activeTab=dependents

If we decide to go this way, we may close this ITP.

Thoughts ?
