This change makes the 73 variables in ratconst.h actually
inline const, which allows them to move from the mutable .data
section of the executable, and into the read-only .rdata
section instead.
Moving data to the .rdata section has a number of benefits,
such as preventing possible corruption due to stray writes,
or other memory corruption.
Additionally, the initialization at run-time start-up is no
longer needed, so there is also a reduction in the .text
(code) section as well.
As a result the overall size of the Calculator.exe binary
(on x64 Release builds) decreases by 1,536 bytes (or ~1.5 KB)
with no change in behavior other than a small performance benefit.
