Hi, we're looking to use this lib in a commercial project, and whilst checking the licenses noticed that node-smpp depends on findhit-proxywrap (BSD) which depends on findhit-util (GPLv3), meaning any derivative works need to be GPLv3 as well.
I've opened mosano-eu/proxywrap#36 to see about removing that dep, but if that's not possible would you be open to a PR switching to a fork that removes the GPLv3 dep?
