Reconstruct block does not delete temporary directory

[samcrow]

The SparSDR reconstruct block creates a sparsdr_reconstruct_[various characters] folder somewhere every time it runs. It should delete the folder when it is destructed, but it currently does not.

New discovery: When using the block from GNU Radio Companion, pressing the stop button in the toolbar causes the process to exit without deleting the folder.
When using the block from a Python script run from the command line, pressing control-C twice causes the process to exit and delete the folder as it should.

We've made some fixes to the way flowgraphs are stopped in GNU Radio since you identified this issue. They're merged into the maint-3.8 and master branches, so they aren't immediately accessible to you since the gr-sparsdr OOT hasn't been updated for the 3.8 release. If updating is of interest here's a link to the migration guide.
