dialr 0.4.0

Major changes

• Update R dependency to R >= 3.6.0 to match the rJava package (#21).

• The old one-shot phone processing functions have been hard deprecated and will now throw an error (#22). These will be removed entirely in the next major release.

Minor changes

• Move rJava initialisation to .onLoad() instead of .onAttach() (#16). Since dialr is a wrapper for a Java package, rJava has to initialise Java before it will work. Previously, users had to attach dialr with library(dialr) to properly initialise Java. Now rJava is initialised when the package is loaded/referenced, so dialr functions can now be used with the :: notation (e.g. dialr::phone()) without a preceding call to library().

• Remove is_vector_s3() method at the pillar maintainer's request (#19).
