tinytex 0.17

• Missing LaTeX packages can be detected from error messages like ! Package isodate.sty Error: Package file substr.sty not found (thanks, @boltomli, #144).

• Added an argument min_times to tinytex::latexmk() to specify the minimum number of compilation times (thanks, @billdenney, #148).

• The repository argument of tinytex::install_tinytex() is more intelligent now (7ca5e39): if you only provide repository = "http://mirrors.tuna.tsinghua.edu.cn/CTAN/", we will automatically append the path to tlnet so it becomes http://mirrors.tuna.tsinghua.edu.cn/CTAN/systems/texlive/tlnet, which is the actual repository value required by the installer.
