Port Input_file_segy and Output_file_segy to Catch2 tests
Re-implement the Input_file_segy
and Output_file_segy
tests as Catch2 tests.
In particular, eliminate references to the deprecated Object
layer in the tests, instead relying on an IO_driver
implementation which is initialized to a SEG-Y file, and an "inspector" type which provides the equivalent data in a native format.
