bad hyperref links for supp figs

[wsdewitt]

Just wanted to note: with the current supp fig approach, hyperref will erroneously link to main text figures with the same number.

tex-template/main.tex

Lines 14 to 20 in e44558e

	\newcommand{\beginsupplement}{%
	\setcounter{table}{0}
	\renewcommand{\thetable}{S\arabic{table}}%
	\setcounter{figure}{0}
	\renewcommand{\thefigure}{S\arabic{figure}}%
	}

This can be resolved by using a custom counter as shown here.
