- force an emissions timeseries map to intitialise with a pollutant and all details selected - so no longer able to map the activity data and it also means the units are always units of emission - prevented redundant calls to the legendemissions endpoint, which put unnecessary strain on the api - a pollutant is selected by default if there is only one for the dataset, also fixed an edge case where a colour cant be looked up when colouring a timeseries on a map and resulted in an undefined error - fixed - added a hover colour to the embedded chart bars - some minor style changes to opacity slider on map and hover border on download multiselect
