Internal helper that resolves the various ways of specifying which axes
should use a logarithmic scale into a consistent pair of logical flags. It
is exported so that extension packages (such as mizerMR) can reuse it in
their own array plot() methods.
parsePlotLog(log, log_x = FALSE, log_y = FALSE)A list with logical components log_x and log_y.
Either NULL, a single logical (legacy form, toggling only the
y-axis), or a character string containing only the letters "x" and/or
"y" to indicate which axes should be logarithmic.
Default logical flags used when log is NULL.
