Transform value into a consistently cased string representation

Example

iex> Honeybadger.Utils.canonicalize(:User_SSN)
"user_ssn"

Internally all modules are prefixed with Elixir. This function removes the Elixir prefix from the module when it is converted to a string.

Example

iex> Honeybadger.Utils.module_to_string(Honeybadger.Utils)
"Honeybadger.Utils"

Configurable data sanitization. This currently:

• recursively truncates deep structures (to a depth of 20)
• constrains large string values (to 64k)
• filters out any map keys that might contain sensitive information.
