install_github configuration arguments have changed

[NathanSkene]

The way that compilation arguments should be passed to install_github seems to have changed. It now works as:

devtools::install_github("NathanSkene/Rgtsvm/Rgtsvm", configure.args="--with-cuda-home=/usr/local/cuda-10.1 --with-boost-home=/usr/local/boost_1_71_0" )

As opposed to how it is stated in the guide:

devtools::install_github("NathanSkene/Rgtsvm/Rgtsvm", args="--configure-args='--with-cuda-home=/usr/local/cuda-10.1/bin --with-boost-home=/usr/local/boost_1_71_0'" )

Still getting various issues installing that seem to be related to CUDA 10.1 and boost 1.71. Will raise them in seperate issues.
