Trigger email on proc import failure

[RW9]

Before even writing code:
- drop the Excel file format, xls is very old > 10 years and not used anymore.

- drop the proc import, this guesses the data and will be the source of many headaches for you continuing to use it.

Next, define the process:
- Get csv file

- Datastep import CSV

- Using the error automatic variable of the datastep check:

if _ERROR_ then call execute('%Send_Email();'); 

- Have a macro for sending the email.
