When opening a json file using it's -ts-mode, bread-crumb-mode causes a big
performance impact. This performance impact seems to be more than linear i
nrealtion to file size,  doubling in size causes more than doubling the
time until emacs becomes responsible again, likely because it contains more
than double the number of nodes to parse.

Many other popular editors contain a breadcrumb-feature and having that
feature for json, yaml, xml, ... files seems "natural".
