Clang-format already has an `IntegerLiteralSeparator` option that adds separators to integer literals. When I started using it, it confused me there was no alternative for floating point literals.
It would be great to either:
1. Add a new option called `FloatingPointLiteralSeparator`, which would do the same as its integer alternative, only for floating point literals.
2. Expand the existing `IntegerLiteralSeparator` to apply the formatting to floating point literals.
I was imagining something like:
```yaml
# .clang-format
FloatingPointLiteralSeparator:
Decimal: 3
DecimalMinDigits: 5
Hex: 4
HexMinDigits: 5
```
The resulting format could look like this:
```C
// Before
double decimal = 12345678.12345678e-50;
double hexa = 0x1234567.89abcdfp-100;
// After
double decimal = 12'345'678.123'456'78e-50;
double hexa = 0x123'4567.89ab'cdfp-100;
```
