Adds edge wells documentation and addresses kelshmo comments

[DimmestP]

Fixes #132 and #124

• Adds explicit examples for creating plates with empty edge wells for the create_blank_plate and label_plate_rowcol. I don't think any of the other helper functions can be easily coerced into allowing edge wells (I also dont think we need to change them to enable as user can just create custom plate designs)
• Adjusts function docs title for create_blank_plate, create_blank_plate_96well, and create_blank_plate_1536well to more explicit "Create a blank plate template as a tibble (with helper functions for common plate sizes)"
• Leaves "Nice tick labels for logarithmic axes in ggplot2" as title for five helper functions as I think their relationship is explained sufficiently clearly in docs
• Creates unique functions docs for make_row_names_lc1536 and make_row_names_echo1536
• Adds links to relevant vignettes in label_plate_rowcol doc
• Fixes target-id warning in calculate_efficiency example

The code looks good, but checks are failing due to some missing link.

Could you address?

Warning: Missing link or links in documentation object 'create_blank_plate.Rd':
