refactor core library

much cleaner now, and simpler.
- `span` is an open sum type, so it can carry as much info as we want
from enter to exit. This means most collectors shouldn't even need a
global table for spans!
- merge manual spans and spans. It's just spans now. Keep old
Trace_core.xxx_manual_xxx functions but deprecate them
- add `extension_parameter` to carry additional info to collector (eg
OTEL span kind, TEF sync/async, maybe span links, etc)
- make the collector into a record of callbacks + a state, for
efficiency (but also to make it easier to extend in the future with
callbacks that have a default implementation
)
