Build fails with boost 1.88

[t3kk3n]

Trying to build dump978 with boost 1.88 (maybe issue persists with 1.87 as well?), getting the following errors:

`
==> Starting build()...
g++ -march=armv7-a -mfloat-abi=hard -mfpu=neon -O2 -pipe -fstack-protector-strong -fno-plt -fexceptions -Wp,-D_FORTIFY_SOURCE=3 -Wformat -Werror=format-security -fstack-clash-protection -fno-omit-frame-pointer -Wp,-D_GLIBCXX_ASSERTIONS -std=c++11 -Wall -Wno-psabi -Werror -O2 -g -Ilibs -DVERSION="e827042" -c -o dump978_main.o dump978_main.cc

`

I haven't put much time into trying to figure out what needs to be changed/updated, so figured I'd create an issue first. Compiling on Arch Linux on a raspberry pi 3, not sure what else information is needed? Thanks!

Edit: Not sure why the code block isn't working after attempting to fix indentation/spacing issues?

This branch possibly fixes it: https://github.com/flightaware/dump978/tree/boost-asio-deprecation

(will probably be merged to dev shortly)

#29 (now merged to dev) should fix this
