feat: extended bit window in NetworkFilter

[seia-soto]

This PR introduces a concept of sourceMask to extend mask of NetworkFilter from 32 bits to 48 bits (16+32). With this changes, we are able to keep supporting more options in NetworkFilter.

For the backward compatibility issues, we may accept two kinds of arguments from NetworkFilter then process them separately. For an instance, we can accept number | [number, number] in the argument object of the constructor function. Then we can build two corresponding mask from a single number depending on the previous format if number was given.

if (sourceMask === undefined) {
  // Build two bitmask referring to the legacy format.
  let sourceMask = 0;
  let mask = 0;
  if (getBit(mask, LEGACY_NETWORK_FILTER_MASK.firstParty)) {
    setBit(sourceMask, NETWORK_SOURCE_MASK.firstParty)
  }
  // Do same for all properties
}

With this structure, we can avoid breaking legacies.

Putting this off until we fully utilize 31st bit of network filter mask.
