fix incorrectly escaped pipe in README table
Tera templates support custom functions and filters, and Itsy-Gitsy defines a few for convenience:
-| Name | Type | Purpose | Example | |
-|---------------------|----------|--------------------------------------------|--------------------------------------------------|--------------|
-| only_files | filter | Filter the file tree into only files | {{ all_files \| only_files }} | |
-| only_dirs | filter | Filter the file tree into only directories | {{ all_files \| only_dirs }} | |
-| hex | filter | Output a number as a hex string | {{ 17 \| hex }} | |
-| oct | filter | Output a number as an octal string | {{ 17 \| oct }} | |
-| mask | filter | Bitwise mask a number with another number | {{ 17 \| mask(mask="0x77") }} | |
-| url_string | filter | Convert a string to a url-friendly "slug" | {{ file.path | url_string}} |
-| ts_to_date | function | Convert a timestamp and offset to a date | {{ts_to_date(ts=ts_utc, tz=ts_offset)}} | |
-| ts_to_git_timestamp | function | Same, but print in standard Git format | {{ts_to_git_timestamp(ts=ts_utc, tz=ts_offset)}} | |

`url_string` can be used in conjunction with the `%PATH%` and `%REF%` filename variables. Both use a very primitive form of "slugifying" the strings into a format that can be used in a URL. This allows for basic permalinks.
