dialr 0.4.1

• phone() now pre-processes values that are considered "not a number" to avoid running them through the Java parser. This massively speeds up phone number parsing for "", NA and similar values, and fixes an issue where Java would freeze after seeing a large amount of invalid phone number values (#27).

• It is now possible to create empty phone() vectors (#28).

• show_progress is now a function argument for phone() and get_timezone(). Previously progress bar visibility could only be set package wide using the dialr.show_progress option. Now it can be set locally using the show_progress function parameter (#25).
