Alternate means to ignore layers / text styles

In sketch a symbol may be named `icon / myicon` and another one called `icon / othericon` then they will be grouped together in the `icon` group. Now if I ignore a symbol with `#icon / hideIcon` it will not be grouped with other icons so we need a means to ignore without breaking the grouping like `icon / hideIcon #` or `icon / hideIcon ##` to make sure that no typo occurs. _(maybe a config for the ignore rules?)_

No files or tests are named. Start by locating the plugin logic that parses layer or text-style names for ignore markers and groups symbols, then compare the current `#icon / hideIcon` behavior with the proposed trailing `#` or `##` forms. Done means an ignored symbol remains in its expected group and the chosen syntax or configuration avoids accidental matches.
