launch a V8 session once per function call

[ateucher]

Rather than a session-wide context, launch once per function call. I think that way we should be able to support parallel processing without running out of memory as quickly.

Hi @ateucher

Yes! Please! It will be an elengant solution to

rmapshaper/R/onLoad.R

Line 4 in e7e0b4f

ms <<- V8::v8()

.

Besides I have problem when I try to load the package in knitr a document. So I need to put the library(rmapshaper) out of the rmd document and load before knit the rmardown file :/.

Thanks for this package 💃
