update: accept abnormal resistance as valid row in check-db

- this commits includes 2 other implementations
  - 1st one with custom type with `impl Read` for Lazy evaluation
    - this somehow ended up in infinite loop
  - 2nd one which collects lines without skipped lines first
    - this works
- the current implementations has another File and catches invalid row
  and check the line later
