v0.9.1b2

Issues: #299, #303, #304

• New profile: Growatt 3000-15000TL3-S (Issue #299):
  Added support for the TL3-S three-phase grid-tied string inverter (3–15 kW, legacy protocol).
  Register layout confirmed from a full device scan: PV inputs at regs 3–8 (PV1 voltage/current/power
  and PV2 voltage/current), total AC power at reg 12, per-phase output (R/S/T) at regs 16–25,
  temperature at reg 32, and energy at standalone regs 53/55 (×0.1 kWh). Auto-detected via DTC 2049
  at holding register 43. No VPP support — holding register 30000 returns Illegal Function.
  Note: regs 9–10 contain firmware version bytes (not PV2 power), so PV2 power stays 0; use the
  Total PV Power sensor instead.

• Fix: house_consumption mirrors solar on SPM 8000TL-HU (Issue #303):
  The HU variant of the SPH family does not populate power_to_load or power_to_user registers,
  causing house_consumption to collapse to solar power when both are zero (the simple load = solar
  fallback). Fixed with a full energy balance fallback: when battery or grid data is present,
  house_consumption = solar + battery_discharge − battery_charge + grid_import − grid_export.
  With the HU test case (solar 2389 W, import 2801 W, discharge 501 W) this now correctly
  computes ≈ 5691 W instead of 2389 W.

• New profile: MIC 2500-5500MTL-S (Issue #304):
  Added support for the MIC 2500–5500MTL-S single-phase dual-string grid-tied inverter family
  (2.5–5.5 kW, legacy V3.05 protocol). Inherits the MIC 600–3300TL-X register map with PV2
  voltage and current confirmed at regs 7–8. PV2 power pair at regs 9–10 is included but
  unconfirmed — if the PV2 Power sensor shows an unrealistic value, those registers contain
  firmware version bytes and should be reported via the issue tracker.
  Auto-detected via DTC 210 at holding register 43. Note: this inverter rejects multi-register
  Modbus block reads — use block_size=1 with the Universal Scanner service.
