fix missing configuration error due to change of namespaces

update code to run on the latest yapapi v0.11.0

this is a feature release with a column added that shows whether the provider udp port is open for p2p connections, signified by "public"

due to stats api being no longer documented, only manual probing is supported.
remote retrieval via my own http REST service may be implemented at a later date
subnet is set to "public" for v0.12.0++

fix downloading of stats after change in stats format

• manual probing made easier by not requiring the YAGNA_APPKEY be exported to the environment
• stats now show on hybrid-mainnet
  still clunky af 😋

patch to better parse features (prevent erroneous omissions) using the feature filter from providers on intermediate versions

• when model information is shared its frequency is displayed (e.g. in the case of Intel) or a description of the model is displayed (e.g. in the case of AMD)
• column sorting is enabled for frequency (intel) and naming (amd) separately

• patches a bug where the version heading when clicked is obscured by other columns, now stretched evenly with other columns
• version heading now shown by default

mac os x heading/columns are correctly measured
note: dragging a header little bit off mark might clear results temporarily requiring the header to be clicked to update the screen. (FIXED UPSTREAM)

• can now see memory and storage sorted in the usual way
• raw offer now shows provider name in title

• cosmetic tweak to entry checkbox fields on bottom of window by increasing spacing between: now a bit easier on the eyes.

• add a start filter
• add an update button so users are not as tempted to take the long refresh route if only filtering
• fix feature column widths (balanced when added)
• disable update button on refresh (issue from v0.6.1)
• refactoring

• check for gc_spyu model information locally and exclude column if no model information has been stored.
• use experimental windows gui skin for cleaner appearance on windows
• improved code documentation, refactoring
• python8 compatible for older ubuntu systems etc

manual probe feature broke column sorting, now fixed

patch to prevent manual probing option from being enabled despite lack of availability

manual probing option available when yagna_appkey environment variable set (and yagna is running)

cpu and dur filters should accurately cutoff to include max

• introduced epsilon comparison

results now show a numerical summary of the distribution of rates:
how much ~20% charge at most
how much ~40% charge at most
how much ~60% charge at most
how much ~80% charge at most
across the rates for cpu, env, and start

• mac os view now balanced
• headings less scrunched
