Issue overview

Version 24.1.0 of the software has introduced a novel incompatibility: files lacking an explicit .csv extension are no longer recognized as valid inputs.

A temporary workaround involves manually altering the file extension of external data. Specifically, the file name must be either replaced with or appended by .csv.

For instance, the following block will produce an error:

Schedule:File, 
    Rainfall Data from EPW file,          !- Name
    Any Number,                           !- Schedule Type Limits Name
    weather-file.rain,                    !- File Name
    1,                                    !- Column Number
    1,                                    !- Rows to Skip at Top
    8760;                                 !- Number of Hours of Data

The error is rectified upon modification of the file and its corresponding reference:

Schedule:File, 
    Rainfall Data from EPW file,          !- Name
    Any Number,                           !- Schedule Type Limits Name
    weather-file.rain.csv,                !- File Name
    1,                                    !- Column Number
    1,                                    !- Rows to Skip at Top
    8760;                                 !- Number of Hours of Data

Prior to this release, the system successfully processed files with alternative extensions. Not sure what the purpose of the src/EnergyPlus/InputProcessing/CsvParser.cc is, but for now it represents a regression in software functionality from previous versions, where this issue had been previously resolved.
