dbus-vis: Fix counts for overlapped entries

For dbus method calls that overlap in time, the Render() routine used to
only report counts from the last row. This has been corrected such that
the sum of the counts from all rows belonging to the same same are added
together.

dbus-vis: fix errors and clean up preload.js

This change fixes two errors and does some clean-up:

1. After updating Electron to 11.5.0, "enableRemoteModule: true" is
needed for require('electron').remote to work.

2. Add handler for stderr in parsing output

Sometimes when a Malformed packet is encountered, the error message does
not get out and the parsing process gets stuck. Adding the handlers can
enable the processes to continue executing in these situations.

3. Removed the unused "preload.js" file.

4. Now clicking the time line after panning the time axis will not cause
an accidental zoom-in to an interval starting with -999.

The cause of this bug is due to HighlightedRegion.t1 being set to the
current mouse location by the OnMouseMove function. This can be
fixed by ensuring that MouseState.hoveredSide must be "timeline".

dbus-vis: Initial commit

dbus-vis visualizes PCAP files captured by busctl as well as
text-format outputs from busctl.

dbus-vis displays the visualized results in horizontal
timelines, where each horizontal bar represents a DBus request, or
an IPMI request (an IPMI request is a specific kind of DBus request
sent to the IPMI daemon.)
The requests may be grouped by one or more fields including
type, sender, destination, path, interface, member.

In addition, if the BMC console is available, dbus-vis can connect
to the BMC console and capture DBus/IPMI requests in real time.

dbus-vis is in the form of a web page and is wrapped using Electron
to run as a desktop app.

Basic usage:
* Mouse click and drag:
* If mouse is over time axis: drag timeline horizontally
* If mouse is over vertical scroll bar: scroll up/down
* Otherwise: select a region for measuring time & zooming in
* Mouse Scroll wheel:
* If mouse is over time axis: zoom in/out
* Otherwise: scroll up/down
* Click on the expandable headers will expand/collapse the entries under
that particular header.
