Add support for ldas-tools-diskcache output format 0x0101

In order to support non-GWF file extensions, the gwdatafind server app needs to be able to properly parse diskcache format 0x0101, which will provide the underlying support for other file extensions.

The new format output looks like this:

# version: 0x0101
/cvmfs/gwosc.osgstorage.org/gwdata/zenodo/ligo-virgo-kagra/2022/6477075/1,L,L1_HOFT_CLEAN_SUB60HZ_C01_T1700406_v4,.gwf,1,2591 1652226303 1 {1241849856 1241852447}

while the server (currently) expects something like

/test/path,H,H1_TEST_1,1,8,gwf 1556913881 1 {1000000000 1000000008}
