Added DaysPerMonth to vDateTime
Changed split-recs to accept sets and disallow maps
Fixed vExcept to show (issue-) msg in trace.

When moving to clojure-stack-traces the (issue-)msg was omitted.
Extende edn to contain the form-reader and logging

Extended the form-reader of vinzi.cdp.clojure to also allow
for showing a trace how far it got during reading of it's input.
This way we can pinpoint the location of an error during reading.

Also usefull when reading edn files.
Extended read-end-file to also use extended reporting.

The new function logged-read is introduced, and can either
wrap read-form-aux or edn/read.
simplified get-log-reader-aux

Previously the state was too big. Now state is limited to the
essential part (and the rest is correctly enclosed).
Code becomes easier to read and has less brackets.
