GeneralFIRE

Description
This SOFA convention set is similar to GeneralFIR. The only difference is the DataType, which is FIRE, not FIR. All other attributes and variables follow the general SOFA specifications.
As GeneralFIR, this convention set can be used to save data which are too general to store in more specific conventions.
GeneralFIRE is deprecated; GeneralFIR-E is recommended instead.
Version 1.0
This version follows the conventions GeneralFIR (version 1.0) standardized in AES69-2015. Note that GeneralFIRE 1.0, in contrast to GeneralFIR 1.0, has not been included in the standard, thus, here, we declare it as stable.
