Make "epsg" lower case in initialization string.

(Alternatively could use "+proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0" and avoid EPSG lookup).

Current behaviour

https://github.com/neilcharles/geoviz/issues/27

On Linux: 

 sp::CRS('+init=EPSG:4326')
Error in sp::CRS("+init=EPSG:4326") : no arguments in initialization list

On windows: 

sp::CRS('+init=EPSG:4326')
CRS arguments:
 +init=EPSG:4326 +proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0
