QETZ-DB-FIRST stage 3a. QETProject::openFile() unzipped and joined a .qetz itself and kept what it held beside the document in three members of its own (the entries, each folio's part, the pictures), and writeContainer() split and zipped it. Both now live in their own classes under sources/container: QetzReader reads a .qet or a .qetz and keeps what a .qetz holds for as long as the project is open; QetzWriter writes the document as a .qetz. No behaviour change: the same calls in the same order. This is the seam stage 3b needs, where opening fills the working database straight from project.sqlite instead of rebuilding it from the joined XML.

@brief The QetzReader class

Reads the bytes of a project file, a .qet or a .qetz, into its project
|
|
document, and keeps what a .qetz holds beside that document for as long
|
|
as the project is open: its entries (a save copies the parts of the
|
|
folios not built from them), the part each folio was read from, its
|
|
pictures and its format.
