[Codestyle] Use of spaces around operators

[Flamefire]

I know codestyle is highly subjective, but I'd like to make a suggestion:

Would you mind adopting a codestyle with spaces around operators?
Without those it looks like a token soup that is hard to parse visually for me.

E.g.:

• for(std::size_t i=0;i<k/8;++i){
• x?1+constexpr_bit_width(x>>1):0;
• x|=Block(1)<<(h&mask);

could be:

• for(std::size_t i = 0; i < k / 8; ++i){
• x ? 1 + constexpr_bit_width(x >> 1) : 0;
• x |= Block(1) << (h&mask);

Or at least for "delimiters"

• for(std::size_t i=0; i<k/8; ++i){
• x ? 1+constexpr_bit_width(x>>1) : 0;
• x |= Block(1)<<(h&mask);

To me this makes it much easier to see which parts belong together and not miss e.g. the "?", "|" or ";"

Great library but could use clang-format as part of CI 👍
