New version: SMLMData v0.6.0

[JuliaRegistrator]

• Registering package: SMLMData
• Repository: https://github.com/JuliaSMLM/SMLMData.jl
• Created by: @kalidke
• Version: v0.6.0
• Commit: 51d80bf2df43dcb8f06eebc9984cba42d25c00d2
• Reviewed by: @kalidke
• Reference: JuliaSMLM/SMLMData.jl@51d80bf#commitcomment-176015541
• Description: Data types and utilities for SMLM coordinate data.
• Release notes:

## Breaking changes

- **Emitter2DFit**: New `σ_xy` field added between `σ_y` and `σ_photons` for x-y covariance
- **Emitter3DFit**: New `σ_xy`, `σ_xz`, `σ_yz` fields added for full 3D covariance matrix

## Migration

Use the keyword constructor which remains backward compatible:
```julia
Emitter2DFit{T}(x, y, photons, bg, σ_x, σ_y, σ_photons, σ_bg; σ_xy=0.0, frame=1, ...)
Emitter3DFit{T}(x, y, z, photons, bg, σ_x, σ_y, σ_z, σ_photons, σ_bg; σ_xy=0.0, σ_xz=0.0, σ_yz=0.0, ...)
```

All JuliaSMLM ecosystem packages tested and compatible.
