Document EDZ import: zero wiki coverage of a whole import format
sources/import/edz/ is ~1,150 lines (excluding the vendored LZMA SDK)
implementing import of EPLAN Data Portal parts, and the word 'EDZ'
appeared nowhere on the wiki -- not a passing mention, not a features
bullet, nothing.
The module already carries a thorough developer README; this restructures
it for the wiki rather than writing from scratch, verified line-by-line
against the source: the menu path, the exact field mapping (manufacturer,
order number, description and comment land in the same four
element-information fields the BOM already reads), the zip-vs-7z format
detection and its current 7z-only limitation, and the point most likely
to surprise a user -- the imported symbol is a generic generated
rectangle, not a copy of the EPLAN macro's geometry, because that
geometry is tokenised EPLAN PXF referencing EPLAN's own libraries with
nothing portable in it.
Also carries the module's EPLAN Data Portal Terms of Use notice forward,
framed as a description of what QET's reader does (parses only portable
factual data, reproduces no EPLAN-proprietary geometry) rather than legal
advice about the reader's own situation.
