Error message if input or output files don't exist / aren't writable #10

Closed tmaklin closed 7 months ago

tmaklin commented 1 year ago

running the below command if the file design_matrix.csv does not exist should crash when reading the inputs:

cpprate --beta-draws beta_draws.csv.gz -x design_matrix.csv --threads 4 --id-start 0 --id-end 1

but instead gives error

Checking the files can be handled with the standard library \<filesystem> headers since we require c++17 to build anyway.
