Trk::Parameters, move remaining methods on the .icc files, add compile time check on Charged/Neutral

• move remaining inline methods from the .h to the .icc files. Then do a format also of .h

• The DIM (N) is known at compile time and there was already a constexpr variable for it.

• In reality we only have Charged or Neutral Parameters (the T in the template list) .In C++17 We can enforce this also at compile time Also we can have a constexpr method that can also tell what was used isCharged

• Add 2 tests to test the dim and isCharged

• It seems that clang-tidy prefers using rather than typedef as "modern" style.
