v4.1.0

Fixed

• Slat positions on HmIP blind actuators (HmIP-FBL, HmIP-BBL,
  HmIP-DRBLI4, ...) can now be set through the value/set-value nodes:
  the actuators accept but ignore a lone LEVEL_2 write, so writes to
  LEVEL_2 are transparently remapped to the COMBINED_PARAMETER
  datapoint (L2=<percent>), which is what the CCU itself sends.
  Verified against the CCU's own commands and in unit tests, not yet on
  a physical actuator — feedback in the issues is welcome. (#136, #154,
  #175)

Changed

• binrpc 3.3.2 -> 4.2.0: zero runtime dependencies (the unmaintained
  binary/put packages are gone from the whole tree), fragmented TCP
  frames are reassembled correctly (previously a header split across
  chunks caused "malformed response" errors or a hanging request), and
  truncated payloads no longer throw from inside socket handlers.
• New maintainer tooling for the shipped device descriptions:
  tools/paramsets-fetch.js fetches paramset descriptions from a live
  CCU, tools/paramsets-join.js merges dumps (including
  user-contributed paramsets.json files from issue reports). See
  docs/paramsets.md.
• Device descriptions refreshed from two lab CCUs on firmware 3.89.8:
  58 new entries (HmIPW-DRAP 3.0.36, HmIP-PDT 1.4.8, HmIP-WRC2 1.0.3,
  HmIP-RFUSB, RPI-RF-MOD, the CCU's own HM-RCV-50 / HmIP-RCV-50
  channels) and 9 refreshed ones (HmIPW-DRI16 1.2.2 and HmIPW-DRS8 1.2.4
  now include COMBINED_PARAMETER and the PRESS_* datapoints the current
  firmware reports). paramsets.json is now key-sorted, which makes this
  one diff large but future ones minimal.
• Device descriptions regenerated from the maintainer's production CCU3
  (firmware 3.87.6, ~70 device type/firmware combinations across
  BidCos-RF, BidCos-Wired, HmIP and heating groups): 547 new entries and
  32 refreshed ones. New, among others: HmIP-FBL 1.8.12, HmIP-BSL 1.0.2,
  HmIP-BSM 1.18.14, HmIP-DRSI4, HmIP-MOD-OC8, HmIP-MP3P, HmIP-SRH 1.2.12,
  HmIP-STHD / WTH-1 / WTH-2 2.8.10, HmIP-WRC6 2.2.14, HmIP-eTRV-2 2.2.8,
  HmIP-eTRV-B-2 R4M, HmIP-eTRV-C / C-2 1.4.14, HMIP-PSM 2.22.8,
  HMIP-SWDO 1.18.10, HMIP-WRC2 1.18.x and the HmIP-HEATING 2.0.0 group.
  Devices of these types no longer need a live paramset fetch before
  their channels show up in the node configuration dialogs, and the
  refreshed entries carry the CONTROL hints the current firmware sends.
