Describe your pull request here

---

Please read the guidelines for Bioconda recipes before opening a pull request (PR).

• If this PR adds or updates a recipe, use "Add" or "Update" appropriately as the first word in its title.
• New recipes not directly relevant to the biological sciences need to be submitted to the conda-forge channel instead of Bioconda.
• PRs require reviews prior to being merged. Once your PR is passing tests and ready to be merged, please issue the @BiocondaBot please add label command.
• Please post questions on Gitter or ping @bioconda/core in a comment.

Please use the following BiocondaBot commands:

Everyone has access to the following BiocondaBot commands, which can be given in a comment:

@BiocondaBot please update	Merge the master branch into a PR.
@BiocondaBot please add label	Add the please review & merge label.
@BiocondaBot please fetch artifacts	Post links to CI-built packages/containers. You can use this to test packages locally.

For members of the Bioconda project, the following command is also available:

@BiocondaBot please merge

Upload built packages/containers and merge a PR. Someone must approve a PR first! This reduces CI build time by reusing built artifacts.

Also, the bot watches for comments from non-members that include @bioconda/<team> and will automatically re-post them to notify the addressed <team>.
