Chandrayaan2 DB Errors

[acpaquette]

The chandrayaan2 database json seems to have hold overs from the chandrayaan1 database file. The main issues seem to be that the IAK kernels are held over from chandrayaan1:

    "ohrc" : { 
        "iak" : { 
            "kernels" : ["mrffrAddendum[0-9]{3}.ti$"] <--- Should be "^ohrcAddendum[0-9]{3}.ti$"
        },
        "ik" : { 
            "kernels" : ["^ch2_ohr_v[0-9]{2}.ti$"]
        },
        "deps" : ["/chandrayaan2"]
    },

Then we are pulling chandraayan1 spks into the tmc2 area:

    "tmc2" : { 
        "iak" : { 
            "kernels" : ["^tmc2Addendum[0-9]{3}.ti$"]
        },
        "ik" : { 
            "kernels" : ["^ch2_tmc_v[0-9]{2}.ti$"]
        },
        "spk" : {  <----- This should not exist
            "reconstructed" : {
                "kernels" : ["M3.*_V03_L1B_nadir-jig_2016-04-29.bsp$"]
            }
        },
        "deps" : ["/chandrayaan2"]
    }

Finally, chandrayaan2 should also look for the ch2_eph kernels for the spks:

    "chandrayaan2" : {
        "ck" : { 
            "reconstructed" : {
                "kernels" : ["^ch2_att_[0-9]{2}[A-Za-z]{3}[0-9]{4}_[0-9]{2}[A-Za-z]{3}[0-9]{4}_v[0-9]+\\.bc$"]
            }
        },
        "fk" : { 
            "kernels" : ["^ch2_v[0-9]{2}.tf$"]
        },
        "sclk" : { 
            "kernels" : ["^ch2_sclk_v[0-9]+.tsc$"]
        },
        "spk" : { 
            "reconstructed" : {
                "kernels" : ["^ch2_orb_[0-9]{2}[A-Za-z]{3}[0-9]{4}_[0-9]{2}[A-Za-z]{3}[0-9]{4}_v[0-9]+\\.bsp$"] <--- should be changed to "^ch2_[orb|eph]_[0-9]{2}[A-Za-z]{3}[0-9]{4}_[0-9]{2}[A-Za-z]{3}[0-9]{4}_v[0-9]+\\.bsp$"
            }
        }
