Installation Challenges

[samgdotson]

I attempted installing plutus on a fresh installation of Ubuntu 20.04 and ran into two obstacles:

1. install.packages('devtools') failed because it required additional libraries. I resolved the issue using

   sudo apt install build-essential libcurl4-gnutls-dev libxml2-dev libssl-dev

2. install.packages('JGCRI/plutus') failed because it could not find xml2 (i.e. the XML dependency was failing). I resolved this by using

   sudo apt-get install libxml2-dev

   I'm not sure why I had to install libxml2-dev twice, but I was able to install plutus after that.

This issue can be closed when:

• [x] the README.md file includes additional guidance for linux users.

Hi @samgdotson , thank you for finding out the issues of installing plutus on Linux. I updated README to include instructions on installing additional libraries on Linux.
