Bug Fixes for Elements

• There was a bug in the ECOL element when the length was nonzero and the offset (DX or DY) was nonzero. This was fixed.
• To avoid numerical problems, synchrotron radiation is now disabled automatically for KSEXT elements shorter than 1 $\mu$m when performing beam moments calculations with radiation.
• In some cases, the matrix for the MATR element would not get loaded prior to tracking, resulting in a crash. This was fixed.
• A bug was fixed in post-adjustment of synchrotron radiation losses in the CSRCSBEND element, which made extremely small errors in the results This was reported by K. Amyx (Tech-X).
