Pull Request Overview

The PR updates the OpenWrt ASCII logo and introduces a 'small' variant, which aligns with official branding. While Codacy analysis indicates the code is up to standards, the review identified a critical preprocessor guard mismatch in src/logo/ascii/o.inc that may cause build failures if logos are selectively excluded. Additionally, there is a gap in the logo discovery logic that prevents the small variant from being easily accessed via standard CLI flags. Addressing these issues is necessary to ensure build stability and expected functionality.

About this PR

• The PR lacks automated unit or integration tests to verify the rendering of the new logo variants. Future changes to ASCII processing or color mapping might break these designs without immediate detection.

Test suggestions

• Verify that the 'openwrt' large logo renders correctly with the defined two-color palette (White/Blue).
• Verify that the 'openwrt_small' logo renders correctly with the defined two-color palette (White/Blue).
• Verify that the build system correctly identifies and includes the new 'openwrt_small.txt' data macro.

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Verify that the 'openwrt' large logo renders correctly with the defined two-color palette (White/Blue).
2. Verify that the 'openwrt_small' logo renders correctly with the defined two-color palette (White/Blue).
3. Verify that the build system correctly identifies and includes the new 'openwrt_small.txt' data macro.

Let's keep the old logo as openwrt2 in case someone like it.

Thanks.

I'm about to cut a hotfix release, so v2.64.2 will have this one
