electrochem: Modulo-bat new format. (#97)

* Remove mgr file

* silence logging flag values.

* Patch parsing of 67-parameter MB files.

Parameter is between E_range_max and I_range. Meaning unknown.

* Rework _technique_dtype -> _technique_dtypes.

* Identified unknown parameter as current/potential using mps file.

* Add test.
