A small utility to clean up delimited data to make it consumable by standard unix tools.

## Search words

Clean tsv data.
Clean csv data.

## Overview

Under the hood this uses the `csv` crate to parse data as a CSV, respecting quoting and escaping rules. For each field 
`cleanse` will then try to do the following three things:

1. Inside a field, replace any instances of the `delimiter` character with ` `.
2. Inside a field, replace any instances of the terminator `\n` character with ` `.
3. Inside a field, replace any malformed UTF8 with the utf8 replacment character.

If any changes were made to a field a log entry is made with the record number, field number and changes.


## Example

```bash
$ cat data.tsv | cleanse -o cleansed.tsv -
