Fix redefinition of 'T`gensymXX' error
...
In rare instances, the Nim compiler will generate the same
symbol more than once. Adding a block works around this issue.
Reproducing this behavior in a unit test has proved elusive.

Fix deprecation warning when importing errorban inside the library
...
`errorban` module [has been deprecated][deprecation] since v0.5.0.
The library continued to use it internally, but because of that, it
was triggering its own deprecation warning. This commit splits
`errorban.nim` into two pieces: the warning and actual code.
[deprecation]: https://github.com/status-im/questionable/commit/e66cd2439b

Rename chaining and indexing operators
...
Chaining operator is now `.?`
Indexing operator is now `.?[]`
Reason: interoperability with the binding `=?` operator.
Chaining and indexing now have lower operator precedence
than binding, ensuring that expressions such as `if a =? b.?c`
work as expected.
