Feature Request: show_label= parameter on bootstrap_label

[danielniccoli]

It would be great if bootstrap_label would have a parameter show_label analog to bootstrap_field.
Sometimes I must do some manual work and need a label that is visually-hidden (screen readers only).

I can achieve the same result with label_class="visually-hidden", but I believe that show_label=False has a more homogenous look to it and you don't have to think about the class that is used.
