[log4plsql] Enhancement/Change on purge with given context

[<log...@li...>]

Hi and thanks for the work put into log4plsql!

In my work it's getting a more and more important and convenient way to=20
log technical information e.g. in plsql-migration-tools.

As i already use it simultaneously for different purposes, i would have=20
expected to have purge(pctx) work just on the given context - so my other=20
logs would not be lost.

As purge does just a complete deletion of all log records i would=20
appreciate e.g. a log variant where purge just deletes all records of the=20
given context (as i have written for myself for a special purpose).

What do you think of this enhancement?
