Mixed coordinate type in maps (#219)

* Add support for per-axis coordinate_type in Map

Allow coordinate_type to be a list (e.g. ["regbin", "log_regbin"])
for mixed linear/log axes in regbin maps.

* Fix test to avoid IDW float32 overflow at exact grid nodes

* Unify preprocess into a single method using _log_mask

Replace linear_pos, log_pos, and _mixed_preprocess with one
preprocess() that always uses jnp.where(self._log_mask, ...).

* Guard linear axes from log10/clip in preprocess

Use jnp.where to substitute 1.0 on linear axes before log10,
preventing value corruption and gradient issues when linear axes
contain non-positive values.
