Figure output width for individual hydrographs

[NewGraphEnvironment]

Accidentally put this as NewGraphEnvironment/fish_passage_bulkley_2022_reporting#122 in the wrong repo

the chunk header parm out.width= c("49.5%","1%","49.5%") controls the width of each element called by knitr::include_graphics so removing it allows the hydrograph to fill page
