[Feature Request] Show partition label if available

[wedebe]

Problem:
Currently only the partition number as it is found in sequence on the device is shown

Suggestion:
Use partition's LABEL value if it has one

Also:
If there is more than 1 partition on a device, and it doesn't have a LABEL, show it as (Partition 1)

Sample setup:

blkid:

/dev/sdb1: UUID="uuid" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="uuid"
/dev/sda1: LABEL_FATBOOT="EFI" LABEL="EFI" UUID="uuid" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="EFI System Partition" PARTUUID="uuid"
/dev/sdb3: LABEL="Win10 OS" BLOCK_SIZE="512" UUID="uuid" TYPE="ntfs" PARTLABEL="Basic data partition" PARTUUID="uuid"
/dev/sdb5: UUID="uuid" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="uuid"
/dev/sdb6: LABEL="Data" UUID="uuid" BLOCK_SIZE="512" TYPE="exfat" PARTLABEL="Basic data partition" PARTUUID="uuid"
/dev/sdb4: BLOCK_SIZE="512" UUID="uuid" TYPE="ntfs" PARTUUID="uuid"
/dev/sda2: LABEL="MBP17" UUID="uuid" BLOCK_SIZE="512" TYPE="exfat" PARTUUID="uuid"
/dev/sdc1: LABEL_FATBOOT="1GB FAT32" LABEL="1GB FAT32" UUID="uuid" BLOCK_SIZE="512" TYPE="vfat" PARTUUID="uuid"
/dev/sdc2: LABEL="4GB ext4" UUID="uuid" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="uuid"
/dev/sdc3: LABEL="24GB exFAT" UUID="uuid" BLOCK_SIZE="512" TYPE="exfat" PARTUUID="uuid"
/dev/sdb2: PARTLABEL="Microsoft reserved partition" PARTUUID="uuid"
