package/snagboot: bump to version 2.6.1

Changelog 2.5..2.6:

treewide:
Migrate documentation to readthedocs
Emit more specific error messages for USB permission-based access issues
Add unit tests

snagflash:
Support compressed input files, e.g. *.wic.bz2
Refactor fastboot-uboot logic to factor out common code and improve logging
Automatically detect when oem_run isn't supported by U-Boot, and fallback to ucmd

snagrecover:
Support Renesas RZ/N1 platforms
Support SoC model aliases, and add i.MX8MP alias
Handle relative path prefixes with the -F syntax

Changelog 2.6..2.6.1:

snagrecover:
Correct i.MX93 ROM code recovery which doesn't support control endpoint HID commands
Add multi-board support to AM335x recovery setup script
Add i.MX7Solo support

treewide:
Fix broken links in documentation
Drop Python 3.9 support
Add CI for Python 3.14

One packaging-related change is that Snagboot would now
unconditionally import the bzip2, gzip and lzma Python modules, which
are not necessarily available. Since these are only needed when
compressed images are provided as input, we submitted a patch upstream
to make those imports only when compressed files are provided as
input, relaxing those dependencies.

+Subject: [PATCH] src/snagrecover/utils.py: import compression modules when
+ needed
+
+Commit 4f98bdec5ebeb13d9f851f848c3bd0086ef31eeb ("snagflash: Support
+on-the-fly decompression of input files") has added unconditional
+imports of lzma, bz2 and gzip Python modules, even if compressed input
+files are not used.
+
+Switch to dynamic imports where these modules are only imported
+on-demand. This allows to relax the need to have support for those
+modules in Python, which can be helpful in environments such as
+Buildroot where dependencies are kept to a minimum.
+
+Upstream: https://github.com/bootlin/snagboot/pull/95
+[Thomas: upstream version is different as upstream master branch also
+supports zstd compression, which wasn't supported as of v2.6.1 of
+snagboot]
