Fixed the units of TES standing losses and renamed parameters (#230)

* fixed the units of tes losses and renamed parameters

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* refactor: use per unit/h for store losses

* refactor: revert to %/h for standing loss to reduce number of ndigits

* [pre-commit.ci] auto fixes from pre-commit.com hooks

 ..   The features listed below are not released yet, but will be part of the next release! 
 ..   To use the features already you have to use the ``master`` branch.
 
+* Corrected units for standing losses of TES technologies from per unit to %/hour and changed parameter names from "Energy losses during storage" to "standing losses" as well as "Temperature difference" to "temperature difference" for naming consistency.
+
+
 * Add standing losses as parameters for LTES
