Node < 14 spits circular dependency warning

[vongohren]

I use this lib through transmutes "@transmute/did-key-bls12381". All I do is a simple generate a key. But upgrading my node version to run the test I get these warnings.

Have you guys seen it before? Does not exist on 12.22.
Does this make sense to you guys?

I do guess this warning comes out of this lib as it is the only mentioned in the stacktrace

Some sources of the error is found here: nodejs/node#32987

@vongohren this should be address in #84, I still have a couple of items to address before the next stable release, however if you need it sooner, the fix should be available in 0.5.1-unstable.ec016ef.

@tplooker looks good to me! Thanks for an early access
