[log_ref] support for stack traces and some engineering (ttiimm#18)

Stack traces are not part of a log message format string,
so we need to separate them out.  This change adds a
regex that is run over the body to pull out Python/Java
backtraces.  If a trace is detected, it is stored in the
`trace` field of the `LogDetails` struct.  The `body`
field will then only contain the message body without
the trace.

In order to support this, though, the CLI needed to be
modified to handle multi-line messages.  So, the binary
now reads input line-by-line and checks if it matches
the log format.  If it does, it's considered the start
of a new message.  If the next line/EOF also matches
the format, then we process the message.  Otherwise,
we add the line to the previous lines to be processed
later.

Files:
* Cargo.toml: Add colored_json to color the output and
  make it readable.
* package.json: Make pnpm version less specific
* debugAdapter.ts: Change "--end" to "--count"
* lib.rs: Add more LogError variants.  Separate a
  backtrace from the message body.
* main.rs: More error checking/reporting.  Process input
  line-by-line and support multi-line messages.
  Color JSON output to make it easier to read.
  Command argument changes:
  - Support multiple source directories
  - Change --end to --count to avoid issues with end
    being less than start or having to figure out
    whether it's inclusive/exclusive.
