[FEATURE] <accepting both long and wide formats for IAQ data>

[Botato12]

The air quality data related to individual VOCs or biocontaminants can come in either long or wide format, depending on the lab performing analysis. It will be a great relief for the contributors if we can accept both formats. Here are two examples.

Typical long format looks like this: Every individual pollutant takes a row, with name and concentration in separate columns. Sometimes there can be an additional column of CAS number and another column of concentration in a different unit.

Typical wide format looks like this: Every individual pollutant takes a column, with unit stored in a separate column. If CAS number is also available, it will be in the header (e.g., the 2nd row following pollutant name).
