API and behavior changes

When creating BEM surfaces via :func:`mne.bem.make_watershed_bem` and :func:`mne.bem.make_flash_bem`, the copy parameter now defaults to True. This means that instead of creating symbolic links inside the FreeSurfer subject's bem folder, we now create "actual" files. This should avoid troubles when sharing files across different operating systems and file systems (:gh:`10531` by `Richard Höchenberger`_)
The ordering of channels returned by :func:`mne.io.read_raw_nirx` is now ordered by channel name, rather than the order provided by the manufacturer. This enables consistent ordering of channels across different file types (:gh:`10555` by `Robert Luke`_)
For :func:`mne.viz.plot_topomap`, :func:`mne.viz.plot_evoked_topomap`, :func:`mne.viz.plot_arrowmap`, :func:`mne.viz.plot_ica_components`, :meth:`mne.Covariance.plot_topomap`, :meth:`mne.Evoked.plot_topomap`, :meth:`mne.Evoked.animate_topomap`, :meth:`mne.decoding.CSP.plot_patterns`, :meth:`mne.Projection.plot_topomap` and :meth:`mne.preprocessing.ICA.plot_components` the topomap image interpolation was previously a cubic interpolation but now can be 'linear' and 'nearest' as well. Unless image_interp='nearest' is passed mne uses a subsequent matplotlib bilinear interpolation to make the interpolated image smoother. Previously, 'image_interp' controlled this second interpolation step and, for the first interpolation, the only option was cubic. To simplify, image_interp is now responsible for the main interpolation and the subsequent matplotlib image interpolation is bilinear but can be changed afterward using im.set_interpolation (:gh:`10617` by `Alex Rockhill`_)
The FLASH BEM surface generation via :func:`mne.bem.make_flash_bem` or the :ref:`mne flash_bem` command has now been clarified in terms of expected inputs. In :func:`mne.bem.convert_flash_mris` the convert parameter is now deprecated and the flash5 and flash30 now accept list of file names or nibabel images. One breaking change is that now the flash files are looked for as mef05_*.mgz and mef30_*.mgz in mri/flash folder (:gh:`10715` by `Alex Gramfort`_)
:func:`~mne.viz.plot_compare_evokeds` gets a new parameter time_unit which can be "s" or "ms" (:gh:`10950` by `Daniel McCloy`_)
The to_data_frame methods for :meth:`Raw <mne.io.Raw.to_data_frame>`, :meth:`Epochs <mne.Epochs.to_data_frame>`, :meth:`Evoked <mne.Evoked.to_data_frame>`, :meth:`SourceEstimate <mne.SourceEstimate.to_data_frame>`, :meth:`EpochsTFR <mne.time_frequency.EpochsTFR.to_data_frame>`, and :meth:`AverageTFR <mne.time_frequency.AverageTFR.to_data_frame>` all now have default time_format=None (keep time in seconds) instead of time_format='ms' (convert time to milliseconds) (:gh:`10925` by `Daniel McCloy`_)
:func:`mne.Evoked.decimate` now aligns to the sample at time=0 (so that the exact sample when the event occurred is preserved) to be consistent with :func:`mne.Epochs.decimate` (:gh:`10945` by `Alex Rockhill`_)
