Route function requires the pbapply package

[Robinlovelace]

Reproducible example:

> remove.packages("pbapply")
Removing package from ‘/usr/local/lib/R/site-library’

Restarting R session...

> routes = route(l = desire_lines_top, route_fun = cyclestreets::journey, plan = "balanced")
Error in route(l = desire_lines_top, route_fun = cyclestreets::journey,  :

Most common output is simpleError
These routes failed: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20
The first of which was:
<simpleError in ldf[i, 1:2]: invalid subscript type 'list'>
Returning list

This caused issues in the geocompr book geocompx/geocompr#607 and the actdev project cyipt/actdev#156 and probably numerous other issues that were not reported.
