Add first functions to support reading Camtrap DP

[peterdesmet]

read_camtrap_dp()

• Will abort if an unrecognized version is supplied. This stops unnecessary reading of files
• Read a dataset (with frictionless::read_package()
• Reads data as df
• Converts to latest version if necessary using convert()
• Has a test for unsupported versions

convert()

• Will convert a dataset to the latest version
• Currently only supports one Camtrap DP version (1.0), so no conversion is done, but the template is there to support it in the future

version()

• Inspired by camtraptor::get_version()
• But also requires camtrap-dp to be present
• Can also derive the version attribute
• Does not have stringr dependency
• Has tests
