echor 0.1.5

Minor Changes

echoGetEffluent() and downloadDMRs() return columns (or nested columns) as characters only.

echoGetEffluent() uses a different API call to returns a flat dmr report (one plant at a time). Existing arguments remain the same and still returns a dataframe. (closes #37)

Single function returns air and water data; echoGetFacilities() and echoGetReports() wrap the individual functions to streamline functions that users need to be familiar with. (closes #33)
Added echoWaterGetMeta() and echoAirGetMeta() functions to retrieve column metadata returned by echoWaterGetFacilityInfo() and echoAirGetFacilityInfo(); specify columns returned by respective functions by including qcolumns argument in respective functions. (closes #28).
Added default qcolumns argument to echoWaterGetFacilityInfo() to ensure reasonable default columns are returned (#29).
echoWaterGetFacilityInfo() properly returns large datasets. The new internal function getDownload() downloads the entire CSV of queried data as a dataframe (closes #27).
Added default qcolumns argument to echoAirGetFacilityInfo() to ensure reasonable default columns are returned (#29).
echoAirGetFacilityInfo() properly returns large datasets. The new internal function getDownload() downloads the entire CSV of queried data as a dataframe (closes #27).
echoSDWGetSystems() downloads data for public drinking water systems.
echoSDWGetMeta() downloads metadata for columns returned by echoSDWGetSystems()
Unit tests for functions that rely on EPA ECHO API utilize skip_on_cran() instead of httptest::with_mock_API()
Imported functions are called explicitly eg. pkg::fun()
