Bycon

* fix of `plotType` parameter as separate one (used in byconaut)
* fix of wrong parameter mapping for `geo:GSM....` filters
- filter definition still pointed to `external_references.id` instead of
`analysis_info.experiment_id`
* `byconaut`: move to general use of `byc["form_data"]` for arguments (_i.e._
requiring the command line arguments to have been parsed into this object)
* fixed the `byconaut` `cytomapper` service by adding `cyto_bands` and `chro_bases`
to the list of `variant_pars`

Bugfix release. Some default values provided in `argument_definitions.yaml`
file were overriding pre-processed values, leading to e.g. to an
endless loop in the handover generation.

* argument parameter redesign
- definition of all parameters/arguments (web & local) in `argument_definitions.yaml`
- parameters not defined there will not be processed anymore (however, there are some
placeholders like e.g. `mode` or `key` which are not utilized by standard methods
and can be co-opted for custom inputs)
- plot parameters are provided as a single string to `plotPars`, with individual
parameter pairs concatenated by `::`
* in GET: `plotPars=plot_chros=8,9,17::labels=8:120000000-123000000:Some+Interesting+Region::plot_gene_symbols=MYCN,TP53,MTAP,CDKN2A,MYC,ERBB2::plot_width=800`
* in CMD: `--plotPars "plot_chros=8,9,17::labels=8:120000000-123000000:Some Interesting Region::plot_gene_symbols=MYCN,TP53,MTAP,CDKN2A,MYC,ERBB2::plot_width=800"`
* modification of the `prdbug` helper

* added handling for user specific granularity permissions
- so far `user_name` is just taken from a form parameter and then stored
as `byc` root parameter (through `set_user_name`)
- local processing (`env`) sets this to `local` (and has a default `record`)
granularity
- dataset specific, user specific maximum granularities can be set in
`authorizations.yaml` which can be extended / overwritten from settings in
`local/authorizations.yaml` (similar to `beacon_defaults.yaml` etc.)
- future updates are planned to handle proper interpretation of `user_name`
and proof of authorization...
* configuration: the basic parameters from `config.yaml` are now stored as `byc`
root parameters and not kept in a mix of root & `config`

* modified `BeaconDataResponse` to keep the `resultSetsResponse` structure while
remobving the `results` from each set, to allow resuult set specific handover
delivery (labeled as __CUSTOM__)
* moved all cytoband library code into `byconaut` (__FUTURE__ considerations for
this in case Beacon supports cytobands ...)
* `byconaut` plots now directly use the database saamples format for plotting variants,
w/o going through the canonical variant creation (this incurred a **huge** penalty)
* reminder that `byconaut` plots use the `plotType` parameter instead of `output`
* `byconaut` now has a color code mapping for the different (EFO, DUP/DEL ...) variant
types; this allows to assign custom `plot_dup_color` etc. parameters while keeping
the available variant types (`variant_state.id`) separated (see `byconaut -> local.plot_defaults`)

* more removal of non-standard components into `byconaut`, e.g. for file generation
such as `.pgxseg`
* adding experimental `target` field to items in `filtering_terms` response
* adding `aminoacidChange` and `genomicAlleleShortForm` to request parameters
(this was a bug fix - they were already activated but not in the `.json` version)
