Channel Alarm PVP Filters Simplification

[versx]

Changes channel alarm Pokemon PvP filters to accept an object with one filter for the specified league instead of a list.

Current implementation:

    ...
    "pvp": {
        // Add or remove any PVP league filtering keys
        // depending on the interested ranks
        // Little league rank filtering
        "little": [{
            // Minimum rank of #1 for PVP rank stats
            "min_rank": 1,
            // Maximum rank of #5 for PVP rank stats
            "max_rank": 5,
            // Minimum CP value of 400 for PVP rank stats
            "min_cp": 400,
            // Maximum CP value of 500 for PVP rank stats
            "max_cp": 500,
            // Minimum PVP product stat
            "min_percent": 90,
            // Maximum PVP product stat
            "max_percent": 100,
            // Gender filtering requirement (*, m, or f)
            "gender": "*"
        }],
        // Great league rank filtering
        "great": [{
            "min_rank": 1,
            "max_rank": 5,
            "min_cp": 1400,
            "max_cp": 1500,
            "gender": "m"
        }],
        // Ultra league rank filtering
        "ultra": [{
            "min_rank": 1,
            "max_rank": 25,
            "min_cp": 2400,
            "max_cp": 2500,
            "gender": "f"
        },{
