report_participants: allow "Female" and "Male" for variable "gender"

[rempsyc]

report_participants allows Female and Male for variable sex, but not variable gender (they are currently coded as non-binary). Yet, variable gender supports the abbreviations for M and F. For consistency, it would make sense to allow their full spelling as well. Plus, some datasets do use Female and Male for variable gender (regardless of one's opinion on whether this is appropriate). It is not a big deal to recode it manually in our own script, but it would be a nice and easily implementable convenience to support this.

Desired updated documentation:

gender	
The name of the column containing the gender of the The [delete typo] classes should 
be one of c("Man", "M", "Male", "Woman", "F", "Female", "Non-Binary", "N"). Note that 
you can specify other characters here as well (e.g., "Gender Fluid"), but the function 
will group all individuals in those groups as "Non-Binary".

Edit

Actually, it seems that (despite the documentation), "M" for "Man" is supported, but "F" for "Female" is not (only "W" for "Woman" is). Demo:

library(report)
data <- data.frame(
  "Age" = c(22, 23, 54, 21, 8, 42),
  "Sex" = c("Intersex", "F", "M", "M", "M", "F"),
  "Gender" = c("N", "F", "F", "M", "M", "M")
)
report_participants(data)
"6 participants (Mean age = 28.3, SD = 16.6, range: [8, 54]; Sex: 33.3% females, 50.0% males, 16.7% other; Gender: 0.0% women, 50.0% men, 50.00% non-binary)"
