d30e705f83 fix most (all?) the places where string<->double conversions are performed 
strod / stod / to_string and all related friends are dependant on current locale for how they format a number

dfb8f1518e Revert "redo serialisation by using a sorted vector instead of a lookup for each possible row/column combination" 
This reverts commit 63484f8b8f.

63484f8b8f redo serialisation by using a sorted vector instead of a lookup for each possible row/column combination 
Not tested, definitely not as correct as previous implementation

9136d21845 move the simplified cell_reference and cell structs out to a header 
the standard xlnt::cell and xlnt::cell_reference have plenty of extra functionality that just slows things down during (de)serialisation
These intermediate structs can be used to minimise overhead before transforming to the final type

7ba36b5e73 fix dumb bug in input randomiser, add basic double->string benchmarks 
* input randomiser was feeding a constant value previously, now actually randomising
* start to_string with the current method (sstream), an faster more correct version (sstream_cached), snprintf, and std::to_chars
** NOTE: only std::to_chars and sstream_cached are correct in the face of locales

0adb8a69b1 add micro benchmarking project, setup number parsing benchmark 
relating to previous work https://github.com/tfussell/xlnt/issues/422
Results are matching what was observed at the time ^^ was being worked on
std::from_chars is included as the target to beat, but since only MSVC has it for floating point it's not
hugely useful yet

uniform real distribution is probably a horrible choice, and it might be good to randomise the number
of sf in each string also (currently the y all end up at max length)

Adam Hooper
ac18fc6dde Parse inlineStr values 
inlineStr XML structure is <c><is><t>. This was being parsed incorrectly
when streaming (because has_value wasn't being set to true) and when
reading the whole file (because the <t> was ignored).
