This is considerably more efficient to read and to update compared to the manually maintained o5m pyramid used so far, at the cost of a lot of disk space. The OSMX usage is extremely primitive so far, relying solely on its command line tool. We could gain a bit more performance still by using OSMX API directly and avoiding the PBF file indirection, but that is in the ~1% range, and technically not entirely straightforward due to how OSMX is built and its bundled dependencies. This code will be used by the upcoming Tirex backend for on-demand tile generation, existing code is only touched for removing a small bit of dead code.
