connection issue with nodejs 17 on system where localhost will resolve by default to an ipv6 address

[rpl]

As described in this README.md the adb.createClient's host option defaults to 'localhost' when not explicitly specified otherwise.

This becomes an issue with nodejs 17, where the default behavior of the dns resolution has been changed to prefer an ipv6 address if one is offered (which varies based on the operating systems and/or how the localhost hostname resolution is configured), see nodejs/node#40537 and nodejs/node#39987.

Other npm packages have had similar issues (e.g. see chrome-launcher issue GoogleChrome/chrome-launcher#251 and the related fix released GoogleChrome/chrome-launcher#253).

As a short term solution, users of this package can explicitly pass '127.0.0.1' as the host configuration option.
