SPIFFS: implement dumping from SPIFFS to client trace buffer

[hazardousvoltage]

Sometimes one has a bunch of traces in SPIFFS after a long day of standalone work, and wants to look at them and decide what to save. Adds '-t' option to mem spiffs dump, to download the data into client trace buffer instead of creating a local file which one must then 'trace load'

Not sure I like how I implemented this, or whether it's useful to anyone else.

You are welcome to add an entry to the CHANGELOG.md as well

Cool,

Only thing I see is that -t vs -s is excluding, when you can use "-t" and "-s" at the same time. Save and load graphbuff.

Just check if there was slen and run that part of the code too.

Hi, thanks for the comments..

-t does not exclude -s, it's excluding -d

Perhaps better, if -t is used, dump only to tracebuffer, but if used with -d, also save to file?

[iceman1001]

yeah,

so to make it perfectly clear how it should work,

-t fill trace
-d save to file

if both params, do both. Meaning we can both save to file and load trace.
if only one, it does what that param intends.

Ignore my comments, this way works well.

Thanks!
