HAVE_STRUCT_TERMIOX definition prevents android build on newer Kotlin and Gradle versions.

[ajeeshklr]

HAVE_STRUCT_TERMIOX definition for android is failing build generation for android for the following Kotlin and Gradle versions.

This is similar to the issue #50

Kotlin version from build.gradle

buildscript {
ext.kotlin_version = '1.8.0'
repositories {
google()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:7.4.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}

gradle-wrapper.properties
distributionUrl=https\://services.gradle.org/distributions/gradle-7.6.1-all.zip

The following code snippet resolves the compilation issue.

android/libserialport/config.h
undef HAVE_STRUCT_TERMIOX

This merge request also contains changes for supporting libserialport 0.3 and the latest flutter_libserialport in pub.
Yaml file is merged with relevant changes.

Functionality of the library is verified in real hardware with these changes.

You might want to rollback the line ending changes, which are a bit noise in your PR

This pr solves the build Thanks :D

Unfortunately, now we are stuck on the permission error as a blocker, Permission denied, errno = 13 you didn't get it?.
