Fix for ROOT-8732

[peremato]

PyROOT cannot read/write C++ class fields of Double32_t. Added the missing converter.

The clang-format got it all wrong :-(

Probably we need to change the coding conventions there...

This kind kind of 'hand formatted' code can/should be surrounded with

// clang-format off
... array declaration
// clang-format on

Probably we need to change the coding conventions there...

I don't think clang-format has a switch for this one ... and we already backtracked on the prior coding convention requesting alignment of operator= across lines (the majority spoke against it), so I don't see this alignment becoming a rule ...

Hi Pere,

Could you also add a regression test for this behavior?

Thanks,
Philippe.
