mapMetadata: check if lookup and domain file are incompatible

[RayStick]

Closes #127

Proposed Changes

• Added a check in mapMetadata to see if a user-specified lookup file is incompatabile with the domain codes (which can be viewed in the plots tab)
• When putting this PR together, I realized the PR template needed updating

To test the code

No Error (using default lookup)

mapMetadata(json_file = 'inst/inputs/national_community_child_health_database_(ncchd)_20240405T130125.json', domain_file = 'inst/inputs/domain_list_demo.csv', look_up_file = 'inst/inputs/look_up.csv')

Error (using intentionally wrong lookup)

inst/inputs/look_up_WRONG.csv is the same as inst/inputs/look_up.csv but with these added lines at the bottom:

TEST,TEST,8
TEST,TEST,-1
TEST,TEST,11

mapMetadata(json_file = 'inst/inputs/national_community_child_health_database_(ncchd)_20240405T130125.json', domain_file = 'inst/inputs/domain_list_demo.csv', look_up_file = 'inst/inputs/look_up_WRONG.csv')

returns:

ℹ Using look up file inputted by user

 ✖ The look_up_file and domain_file are not compatabile. These look up codes are not listed in the domain codes:

[1]  8 -1 11
Error in mapMetadata(json_file = "inst/inputs/national_community_child_health_database_(ncchd)_20240405T130125.json",  :
