Summary description: Bold latin and greek characters through simple prefix characters

Announcement text: ----------------------------------------------------------------------

Description
The boldtensors package provides a highly efficient shorthand for
typesetting Latin and Greek characters in bold and blackboard-bold layouts.
It is specifically designed for the requirements of Theoretical Physics
and General Relativity, where a clear visual distinction between
geometric tensor objects and their components or scalars is essential.

The package uses active characters (~ and ") to keep the source code
clean and readable: - `$~T$` produces a bold tensor T. - `$"R$`
produces a blackboard-bold symbol raY.

Key Features:
rCo Engine Independent: Fully compatible with both classical pdfLaTeX
(using NFSS) and modern LuaLaTeX (using unicode-math and OpenType
fonts).

rCo ISO Compliance: Includes the bt-isodiff sub-package for upright
differential operators according to ISO 80000-2.

rCo Accurate Metrics: Correct placement of subscripts, superscripts, and
accents (like \hat{~T}) by using native math characters instead of
boxes.

rCo Micro-Typography: Preserves perfect kerning and font-specific metrics.
