#2936: CarpetX tsv output does not append files

Reporter: Maxwell Rizzo Status: new Milestone: Version: Type: enhancement Priority: minor Component: CarpetX

CarpetX’s TSV output, excluding the norms/ files, does not append to a single file per group in the way Carpet’s ASCII output does. Instead, it creates one file per group per iteration: `<group>.it000000.<x/y/z>.tsv` for grid functions and arrays, and `<group>.it000000.tsv` for scalars.

Appending subsequent iterations to the same file would make analysis and post-processing easier, while also reducing the amount of output files.
