Add entry points detector

[nisedo]

Hi, it would be great to have a detector that identifies all entry points (public/external non-pure/view functions) and prints them in the report with their modifier if they have one.

To help auditors quickly identify entry points at the start of a new audit.

Hi Alex, I've rethought and refined my idea for generating a report that would help auditors get an overview of the important points of a contract for an audit: https://meowing-earth-cff.notion.site/Aderyn-auditor-report-feature-bc2979ccb971482a9042885e1d03a7c2?pvs=4

Hi @nisedo thanks for feedback. The original plan was to make this output report in an excel sheet. (Tables are excel friendly) :)

But feel free to chime in and give ideas
