The descriptions of the alternate forms of Octal and Binary were swapped
in the doc comment for FormattingOptions::alternate().

single buffer for exponent fmt of integers
No need for fragmented buffers when formatting.
```
orig.txt: fmt::write_i128_exp 143.39ns/iter +/- 0.32
orig.txt: fmt::write_i64_exp 68.72ns/iter +/- 0.03
new.txt: fmt::write_i128_exp 138.29ns/iter +/- 0.50
new.txt: fmt::write_i64_exp 58.93ns/iter +/- 4.62
```
This patch fully eliminates unsafe pointer use (after rust-lang/rust#135265 and rust-lang/rust#136594).

Having `const fn`s that take a `mut &` was unstable until Rust 1.83. Because of
this, not all methods on `FormattingOptions` were implemented as `const`. As
this has been stabilized now, there is no reason not to have all methods
`const`.
Thanks to Ternvein for bringing this to my attention (see [1]).

fmt of non-decimal radix untangled
Have the implementation match its decimal counterpart.
* Digit table instead of conversion functions
* Correct buffer size per radix
* Elimination of dead code for negative
* No trait abstraction for integers
#### Original Performance
```
fmt::write_10ints_bin 393.03ns/iter +/- 1.41
fmt::write_10ints_hex 316.84ns/iter +/- 1.49
fmt::write_10ints_oct 327.16ns/iter +/- 0.46
```
#### Patched Performance
```
fmt::write_10ints_bin 392.31ns/iter +/- 3.05
fmt::write_10ints_hex 302.41ns/iter +/- 5.48
fmt::write_10ints_oct 322.01ns/iter +/- 3.82

address clippy formatting nits
- int_log10.rs: change top level doc comments to outer
- collect.rs: remove empty line after doc comment
- clippy fix: markdown indentation for indented items after line break: a markdown list item continued over multiples lines, but those following lines which are part of the same item are not indented
- clippy fix: bound in one place: when there is a bound in angle brackets and another bound on the same variable in a where clause
