### New Features and Enhancements

Added the `ARKODE_RALSTON_3_1_2` and `ARKODE_TSITOURAS_7_4_5` explicit
Runge-Kutta Butcher tables.

Improved the efficiency of default ARKODE methods with the following changes:

| Type | Old Default | New Default |
| ------------------ | ---------------------------------------------------------------- | ------------------------------------------------------------------ |
| 2nd Order Explicit | `ARKODE_HEUN_EULER_2_1_2` | `ARKODE_RALSTON_3_1_2` |
| 4th Order Explicit | `ARKODE_ZONNEVELD_5_3_4` | `ARKODE_SOFRONIOU_SPALETTA_5_3_4` |
| 5th Order Explicit | `ARKODE_CASH_KARP_6_4_5` | `ARKODE_TSITOURAS_7_4_5` |
| 6th Order Explicit | `ARKODE_VERNER_8_5_6` | `ARKODE_VERNER_9_5_6` |
| 8th Order Explicit | `ARKODE_FEHLBERG_13_7_8` | `ARKODE_VERNER_13_7_8` |
| 2nd Order Implicit | `ARKODE_SDIRK_2_1_2` | `ARKODE_ARK2_DIRK_3_1_2` |
| 3rd Order Implicit | `ARKODE_ARK324L2SA_DIRK_4_2_3` | `ARKODE_ESDIRK325L2SA_5_2_3` |
| 4th Order Implicit | `ARKODE_SDIRK_5_3_4` | `ARKODE_ESDIRK436L2SA_6_3_4` |
| 5th Order Implicit | `ARKODE_ARK548L2SA_DIRK_8_4_5` | `ARKODE_ESDIRK547L2SA2_7_4_5` |
| 4th Order ARK | `ARKODE_ARK436L2SA_ERK_6_3_4` and `ARKODE_ARK436L2SA_DIRK_6_3_4` | `ARKODE_ARK437L2SA_ERK_7_3_4` and `ARKODE_ARK437L2SA_DIRK_7_3_4` |
| 5th Order ARK | `ARKODE_ARK548L2SA_ERK_8_4_5` and `ARKODE_ARK548L2SA_DIRK_8_4_5` | `ARKODE_ARK548L2SAb_ERK_8_4_5` and `ARKODE_ARK548L2SAb_DIRK_8_4_5` |

The default value of `CMAKE_CUDA_ARCHITECTURES` is no longer set to `70` and is
now determined automatically by CMake. The previous default was only valid for
Volta GPUs while the automatically selected value will vary across compilers and
