Add: `hydra-org-template`; remove hydra-org-slide

- Added `hydra-org-template` to interactively expand org Easy Templates
- Replace `hydra-org-slide` with `org-tree-slide-mode-map` specific
  bindings because the hydra doesn't handle (as of today) passing on
  prefixed key bindings like `C-c *`, `C-c -`, etc (which are not bound
  to hydra heads). Using the hydra made it impossible to edit the slides
  using org-mode bindings while the hydra was active.
