tinytex 0.50

• The installation script install-bin-unix.sh will throw an error early if perl is not found (thanks, @jangorecki, #431). Note that on Linux, perl-base is insufficient.

• options(tinytex.tlmgr_update = FALSE) can be set to prevent tlmgr update --self --all when tinytex::tlmgr_install() tries to install packages (thanks, @matthewgson, #434).

• Fixed bugs in tinytex:::auto_repo() that prevented tinytex::install_tinytex() from setting the CTAN repository after installation (thanks, @dmkaplan2000, #436).
