Marc Herbert 53ce8b9d9f logger: new relative timestamps option, relative to first entry seen 
Add a new sof-logger -e 0/1 relative timestamps option where the
TIMESTAMP column is relative to the first entry seen.

Removes many digits and makes the TIMESTAMP column much more readable in
short logs.

Also stop showing "NaN" as the first DELTA like something went
wrong. Show zero instead.

The new option is off by default when using -r(aw) and on otherwise.

The first entry is kept always absolute.
