fgm : fast go version manager

Note: now it's suggested to use mise instead. Because mise can totally replace fgm and do better, so i decide to give up this project.

this project is inspired by fnm

Installation

cargo install fgm or cargo binstall fgm(Suggested)

add the following to your shell profile:

eval $(fgm init)

then you can use fgm to install go versions:

fgm install 1.16.3
fgm use 1.16.3
go version
