Support for stones (mass)

[dominic-ks]

Hello,

Is there the possibility to add support for stones in mass, or perhaps a way to easily extend the functions to add any units that are not supported?

Thanks,

[dominic-ks]

Or of course I can contribute this if it's welcome:

Tnx, I will review the PR in depth later (the code addition is simple) but I am not sure if stones are a proper unit for the imperial system or I have to expand the library so it can accommodate 'historical'(?) units.

Also about the contributions, I am interested to build a proper community to maintain this library but I have to make some improvements to my pipeline for building and npm deployment first.

Hello, stones are definitely a proper imperial unit, and not historical in the UK at least... The standard units for measuring a person's weight, for example, is stones / pounds.
