flopyrw 1.0.3

• [gpkde, get_output, get_data, get_alldata] enable reading from gpkde file written in binary format.
• [gpkde, get_data, get_alldata] improve detection of regular grid while loeading data from gpkde, the is_regular flag requires all cell dimensions of the same size, however, these could be different and the grid still be regular on a per-axis basis.
• [example, gpkde, timeseries] include an example with frequent gpkde reconstruction illustrating the use of a kernels database to speed up the process.
• [gpkde,get_alldata] method to extract the concentration map for simulations including multiple concentration reconstruction time snapshots.
• [test,adv,exponential] include a simple test with exponential advection model
• [src,specified,defaults] in specified (SPEC) source format, improve the handling of default parameters for nspecies, speciesid. clarifies the error message in case that the number of species of given species is not consistent with the specified concentrations.
• [fix,mprwsrc,write_file,cells] it was failing to properly format the cell number while giving cellids (structured=False) to a source, during the writing of the input file.
