fix(from_str, try_from_into): custom error types
...
Remove the use of trait objects as errors from `from_str` and
`try_from_into`; they seem to have caused a lot of confusion in
practice. (Also, it's considered best practice to use custom error
types instead of boxed errors in library code.) Instead, use custom
error enums, and update hints accordingly. Hints also provide
some guidance about converting errors, which could be covered
more completely in a future advanced errors section.
Also move from_str to directly after the similar exercise `from_into`,
for the sake of familiarity when solving.

address review feedback
...
Adjust error text and naming to conform with best practices.
Use `map_err()` instead of `or()`. Wrap lower-level errors instead of
ignoring their details.
Also, don't "cheat" by bypassing the `new()` function in tests.
Fix a dangling reference in the try_from_into hints.

fix: move_semantics5 hints
...
Improve the hints for move_semantics5, as well as the explanatory
comments in the code.
Previously, it was not clear what possible changes were allowed.
It seems that reordering the statements might be the intended solution.
The previous comment about not "adding newlines" doesn't make sense,
so treating it as "adding new lines" makes it more clear.
