The following routines where added or updated to atp_20250822

 1. anc_clean.f
    Cleans the anc derived type.

 2. anc_parse.f
    - Now includes the parsing of all data from an anc file excluding
      comments and datascopes.
    - Another update involves checking for data from versions 2 and 3 of
      the anc file, e.g., opacity and atmospheric brightness temperature.
    - Also accounts for the old version of log2ant (0.96 2021.05.17),
      and the latest version (1.0 2025.08.22)

 3. anc_scav.f
    - Computes the scan average of the TSYS, TPI, and PCAL data as given
      in a ANC derived type.
    - Also accounts for the old version of log2ant (0.96 2021.05.17),
      and the latest version (1.0 2025.08.22)

 4. anc_scav_main.f
    program to parse either a binary or ascii standardized antenna
    telemetry file, compute the scan averages of the TSYS, TPI, and/or
    PCAL and write the output to a so called version 2 anc file.

 5. anc_write.f
    subroutine to write contents of the ANC derived type to file, and
    update the PROVENANCE block (if need be).

 6. atp_scans.f
    updated to include scans from TPI.

 7. bnc_parse.f
    - Akin to anc_parse, it now includes the parsing of data from the
      ANC derived type, and also accounts for the different versions
      of log2ant.

 8. bnc_write.f
    write the contents of the ANC derived type to a binary file, while
    accounting for the different versions of log2ant.

 9. tpi_filter.f
    filters the tpi block for outliers, by either frequency, or time.

10. tpi_stats.f
    compute the average and RMS values of each scan for TPION and
    TPIOFF. At present we assume TPIZERO to be empty, and just assign
    a -999 value.
